Ethylene is a very commonly used chemical raw material in later generations, for the simple reason that it is a very simple structure, and it is one of the simplest among organic matter.

Organic matter is a carbon-containing substance, and of course, to remove carbon monoxide and carbon dioxide, the simplest carbon-containing objects, most of the four carbon elements have a base structure.

The chemical name of ethylene is C2H4, that is, the double-bonded carbon, which is combined with 4 hydrogen atoms, not only has a simple structure, but also has a relatively low molecular weight, and is the simplest organic substance among organic substances.

A simple structure can become a raw material, and other materials can be built into a material for the production of various organic substances.

According to the naming of ethylene, in front of him, there is melene, that is, the chemical formula is CH2, which is not a naturally occurring substance in nature, it is an intermediate substance that reacts with ethylene, and in a natural environment, it will be quickly converted into ethylene.

Naturally occurring in nature, and more simply, methane, which is CH4, is one carbon atom less than ethylene, which is the product of the combination of carbon and four hydrogen atoms, which is a very flammable gas, natural gas, and biogas, which is produced in large quantities.

Methane, ethylene, they are the simplest compounds that occur naturally in nature, and they are relatively stable.

Methane is found in nature, the main component of natural gas is methane, and the main component of biogas is also, which can be found as long as you find some traditional natural gas fields.

With methane and ethylene, a similar reaction can be carried out, which allows researchers to freely combine, add water, hydrogen, oxygen, and then burn, heat, throw some messy things, and experiment with catalysts.

In this way, a variety of organic matter can be produced in large quantities, leaving aside the more complex bases, which in nature are hydrogen and oxygen.

As for hydrogen, in the universe, hydrogen is the most, the first element in the entire universe, but it is almost difficult to appear in nature, and most of the compounds that appear in nature are hydrogen compounds.

After the advent of electricity, hydrogen and oxygen are not a difficulty, electrolysis of water can easily obtain hydrogen and oxygen, between hydrogen and oxygen, the huge difference in specific gravity, hydrogen is easy to float on it, and it is easy to separate.

As long as you do a good separation of the upper and lower levels, you can do a relatively pure hydrogen and oxygen.

These two gases, one as a strong oxidizing agent, can be combined with many substances, under the premise of heating, can be combined with carbon to form a group, can also be combined with oxygen and other substances to form another compound, become a group of mixed organic matter.

Colorful organic matter is produced in this way, even the change of one element will bring about the change of the final organic matter, which can not only help Zhao Xin and light up more cards, but also help Zhao Xin to find more organic matter.

Sometimes, the discovery of organic matter is under such circumstances, continuous production, and the final completion, perhaps, an accident, can produce enough excellent organic species.

Hydrogen and oxygen, as well as some other substances extracted from Dinghaijun, are added to the ethylene mixing experiment, which is the most basic process, and then the deeper reaction is carried out through the change of temperature and the addition of various catalysts.

This kind of reflection is too profound, even Zhao Xin is half-understood, what he can do is to provide funds for the laboratory to try, under the control of different pressures and temperatures, the final product.

To be honest, the subsequent verification experiments, the whole process of the experiment, is quite chaotic, the knowledge structure of this era, the study of organic matter, is still too weak, some of them are like a reaction like hitting the big luck, many times, there are more impurities than the products.

This kind of reaction, in later generations, is meaningless, not even the nature of an experiment, but in the Dinghai Navy, because of the existence of the card system, it is meaningful.

Zhao Xin's card system can light up cards separately from many mixtures, as long as the cards are lit, it means that these things can be made separately, even if this kind of thing can only be generated through the card system.

As long as something is produced, no matter how small the quantity is, it is also produced, and it cannot be industrially produced, but it can be produced in small quantities, and in the laboratory, some of its characteristics are verified, and finally some basic research on certain products is formed, and then used as raw materials, or industrial production.

The card system is quite magical, as long as it is a lit card, it can be generated through energy or other things.

This system, in the early days, before and after the Baozhou Mutiny, became a money-absorbing weapon, without this money, perhaps in the face of the rebels, it can still win, but the price paid is too much.

If you don't have enough money, you won't be able to absorb enough people, and when the time comes, most of the people near Baozhou may be surrounded by the rebels, and then attack the fortress, and Miaojiazhuang may pay a greater price.

After entering the Ding Navy, soap, soda ash, these things, the value created in the end, is a little weak, the current card system, most of them, are occupied by Dinghai coins, the market formed by Dinghai coins, began to seamlessly intervene in the financial field of the Northern Song Dynasty.

The Northern Song Dynasty has not yet formed a financial cognition, perhaps a professional economic official like Ye Qingchen will be a little vigilant, but the Dinghai currency itself has enough value, and the Northern Song Dynasty has fallen into a money shortage, they still recognized it after discovering the real benefits.

What is more profitable than printing money, stainless steel, in the later generations, may be a little more expensive than ordinary steel, but also expensive limited, now it is just that Ding Haijun can not produce on a large scale in the steel plant, the same stamping process is not sound, there is not enough kinetic energy, hold up a stamping machine of sufficient weight, stamping, for the time being, can only be fully produced by the card system.

Even if it is a card system, almost most of the production capacity is controlled by Dinghai coins, and it can still be squeezed out of a certain output, and the purity of the things produced with the card system is above the level, and it cannot be used for production, but it can become a special output, which can be familiar and studied in the laboratory, which can better promote their production and purification.

In chemical reactions, purity is a very important unit, in fact, in many fields, purity is an important factor, for example, in later generations, mushroom bombs, for every 1 increase in purity, the electricity consumed is astronomical, about 30%, at most can be used as fuel, filled into the power plant, but once it exceeds 90%, or even 95%, it will become a weapon-grade, into a terrible weapon.

This is the theory of the mushroom bomb, as early as the beginning of the 20th century, put forward by Einstein, but it was not made until the end of World War II, on the one hand, it is the relationship between the critical point and purity, on the other hand, it is also the relationship of electric energy, the United States almost concentrated a considerable proportion of the country's electrical energy, which was made at the end of the war 3, this kind of weapon, can no longer be calculated by price, at least, the United States 3, each, is more expensive than the same weight of gold.

In the 21st century, with the large-scale development of electricity, electricity is no longer the main problem, but the calculation, as well as the process of various refining, is still difficult, starting from scratch, it is almost difficult, and even to mobilize the whole people, concentrate the vast majority of the country's manpower and material resources.

This is only a theoretical possibility, in fact, in the actual environment of the 21st century, after the five hooligans signed the NPT, almost banned this process, natural uranium ore, the content is quite low, through the natural purification process, can produce 30% of the content of the energy level, it is already good, it needs to pass through the reactor, non-stop reaction collision, under the huge power and computing power, and finally produce weapon-grade raw materials, and then can be equipped.

At a time when satellites are almost all over the world, it is very difficult for backward countries to join this field, and sometimes, newly built reactors are discovered.

The doctrine of a nuclear non-proliferation treaty, and then a series of sanctions, and even wars, at the expense of the production of mushroom bombs, is sufficient.

Ding Haijun is now, there is still a huge distance from the mushroom bomb, and even in addition to the materials of the mushroom bomb, it is quite difficult to refine the other times.

Even in later generations, it is very difficult to purify the material, and some content of raw materials, to purify to a certain extent, is almost an impossible task, sometimes, one decimal place, is an extremely difficult task to complete, let alone two or three decimal places.

In terms of purity, more than 90% of the chemical experiments currently being carried out are meaningless and useless, and if this development continues, it is easy to have a huge impact and affect the direction of research.

But this kind of thing, for Ding Haijun, for Zhao Xin, who has a card system, these experiments are really meaningful, not to mention 90% purity, even if the purity accounts for only about 5%, it can be detected by the card system, and then through a specific method, light up the cards that belong to it.

In chemical production, the purity of more than 90% is a very difficult thing for Ding Haijun, who has a very weak chemical foundation, or even a difficulty like natural hazards, but 5% of the hard work is still possible.

Under the powerful effect of the card system, it shows terrible strength, in Zhao Xin's card system, it belongs to the list of organic matter, and it is gradually lengthened, starting from A, basically all kinds of organic elements within ten are separated and recorded in the card system.

These organic matter within ten is just the foundation of the chemical age, and their appearance has little real effect except for enriching the card system cards.

Methane, that is, natural gas, can be burned by nature, can be made into liquefied gas, enrich the fuel market of the Ding Navy, under the premise that efficiency has become the most important factor in the Ding Navy, the efficiency of coal stoves, compared with liquefied gas, is not a little bit worse.

Chinese mainland, perhaps oil reserves are very low, some large oil fields, buried deep is also very deep, not the strength of the Ding Navy now, can be handled, but natural gas is relatively extensive, as long as in the northwest, in the location of the natural gas field known to Zhao Xin, find a natural gas field, can be large-scale development, laboratory production is completely meaningless.

Most of the other materials are like this, Zhao Xin let the laboratory personnel practice on a large scale, and what they want is to find suitable chemical materials from a large number of chemical reactions, but unfortunately there is none.

Now the search is back to the original point, that is, ethylene, it is the most important chemical raw material in the petrochemical industry, and one of the most important problems lies in polymerization

Polyethylene is the resin product that can be used, and this key point is actually on the poly, which is simple to say, but in fact, it is very difficult.

To put it bluntly, these are two substances, polyethylene, to put it bluntly, is the monomer of ethylene, after polymerization, ethylene, which is itself a small molecule of gas, after polymerization, has undergone a huge change in nature, from gas to solid, and one is carcinogenic, toxic, and at least the surface contact is non-toxic, can be used as food packaging materials

This kind of reflection of aggregation is widely present in nature, for example, carbon element, natural composition of graphite, there are also diamond, are carbon element polymers, but graphite and diamond, these are completely two things, one is soft, one is hard, and the soft kind, and graphene is the king of materials, after reasonable arrangement, its hardness at the molecular level is even higher than diamond.

Of course, polyethylene cannot reach the level of diamond, but the change from gas to solid is also relatively large, and the industrial use of ethylene can only be done after polyethylene, and with polyethylene, some bases of polyethylene are replaced, and polyvinyl chloride is such an excellent material, of course, there are others.

Zhao Xin is a student of history, polyvinyl chloride, polyethylene, he knows everything, but he doesn't know how to polymerize, and he doesn't even know what the polymerization reaction is.

Chemistry at the beginning of high school is destined to be a relatively simple, many are just one or two reaction chemistry, and catalysts will be used in the middle, but this is also a simple catalyst, polyethylene seems to be a reaction under high temperature and high pressure, under the promotion of some catalysts, but what is the specific catalyst, Zhao Xin does not know, this is difficult, maybe you can point out the direction of the future, let the laboratory continue to research, but whether you can get the results, then I don't know, this is a long, must continue to fail, to be able to obtain the process of results.
