In the cards, the lighted soda ash can't be used. In fact, it only causes a little trouble. With soda ash, it can save a few steps at most. With alum oil and sulfuric acid, other acids and bases are not a problem. It is a simple reaction process.
Triacid and dibasic acid are the foundation of modern chemical industry, and also the cornerstone of various types of chemical products in later generations. After liberation, China organized such a battle to lay the chemical foundation. With the help of foreign experts, it basically solved the problem of tri acid and dibasic acid, and cleared the obstacles for the development of chemical industry.
Among the three acids and two bases, there are also different grades. Among the three acids and two bases, the most important and irreplaceable is sulfuric acid, so sulfuric acid is also called the cornerstone of chemical industry.
Without sulfuric acid, other acids and bases are difficult to produce. If hydrochloric acid is produced first, it is unlikely to produce sulfuric acid directly. The activity of hydrochloric acid is not the highest. In a conventional environment, sulfuric acid cannot be replaced.
The conventional environment, that is, there is no high-temperature and high-pressure, no catalyst, no ionic chemistry and other principles. In the specific environment of the Northern Song Dynasty, there is no way to achieve more high-end chemistry.
Zhao Xin is not a professional chemist. His understanding and cognition of chemistry is limited to chemistry at the beginning of high school. He has no ability to use and produce things that are too complex.
Sulfuric acid is the most easily available chemical product and the only acid in ancient China. It can be obtained by calcining alum. In ancient China, sulfuric acid was called alum oil, which also complements each other.
However, the alum oil is only dilute sulfuric acid, which is not widely used. In the Northern Song Dynasty, it was mostly used to remove some rust and wash away some things that are difficult to wash away. At that time, ancient China did not realize that only a simple transpiration could obtain concentrated sulfuric acid.
In fact, it may be found that ancient people did not have a systematic understanding of chemistry. Chemical products, including basic products such as three acids and two bases, are all very dangerous. A little carelessness can be more toxic than poisons and cause more harm.
With sulfuric acid, to be exact, with dilute sulfuric acid, soda ash can be used to transpiration dilute sulfuric acid to 98.5% concentrated sulfuric acid, which is a very traditional and simple reaction.
This is the most traditional method of producing soda ash, which uses sodium sulfate. It is also the only way to produce soda ash since the beginning of chemical manufacturing. It has also been used for many years.
The basis of this method is the use of sulfuric acid, which is highly corrosive to the equipment. In addition, the purity of the finished product is not high, so a series of separations are required to obtain soda ash with ideal purity, which is costly. Later, it was replaced by the more accurate and inexpensive Solvay method.
In the Song Dynasty, Solvay method was the most unrealistic. It required synthetic ammonia, which was a modern method. Before that, ammonia and gunpowder needed natural saltpeter, not nitrogen, which contained the most in the air.
The Solvay method of synthetic ammonia and electrolytic ammonia will use a common energy electricity in the future. Maybe in the future, with finding some permanent magnets and making some magnets artificially, Zhao Xin will let electricity appear in the world. But before that, electricity was still in the hands of the God of Nature. The most basic understanding of electricity is the thunder and lightning in thunderstorm weather, It is too big to add to the great power of heaven and earth.
Before the emergence of electricity, before electricity was effectively used, all electrolysis methods were not suitable. Synthetic ammonia needed not only electricity, but also high temperature and high pressure containers. Even steel making was small in the Northern Song Dynasty. It was difficult to make such containers. The Lubrand process was the only choice.
The main materials of Lublanfa are salt and sulfuric acid. The first step is to complete the mechanical production of sodium sulfate. With natural mirabilite, the process of reaction of salt and sulfuric acid to generate sodium sulfate is subtracted, and sodium sulfate is directly used. In this way, the corrosion of equipment will be reduced to the minimum, and it is not large-scale industrial production. Just light the card.
The biggest effect of the card system is that after lighting up, you can get a certain kind of card through money. Soda ash is the most elementary chemical raw material, which can be found in all natural mines. After the lighting up process is completed, its level must be first, and the price will not be too expensive. In the future, it will be born from a steady stream of soda ash, which is very critical for industrial production.
The biggest difference between industrialization and laboratory lies in the yield and cheapness. Even a simple reaction, if the final quality is uncontrollable and the price is too high, the research will be carried out in the laboratory at most, instead of entering the large-scale production of industrialization.
For Zhao Xin, this is absolutely a cost free thing. He spent 30% more to get a stable Laiyuan. If he steamed steamed buns with soda ash, the amount would be large. Without a stable source, profits and publicity would not be stable, and the profits generated could not be increased.
Maybe later, after having a stable site, Zhao Xin will slowly study and gradually realize the Lubrand method. Before that, it is the only choice to light up soda ash, and then use cards to find soda ash.
Because he had something on his mind, he had breakfast absentmindedly, and the exquisite food did not arouse his appetite at all. At the first time after breakfast, Zhao Xin carefully thought out the steps of the Lubrand soda process.
Skip the process of replacing salt with concentrated sulfuric acid to generate hydrochloric acid and sodium sulfate, go to the next step directly, replace sodium sulfate with charcoal, react with lime at high temperature, and generate soda ash. After dehydration of sodium sulfate decahydrate, it is sodium sulfate, which is available in the card system. The purity is still quite high. It will be very convenient to use and save a lot of time,
After careful recollection and clear thinking of all the key points, Zhao Xin felt that there were no omissions and started to work,
Zhao Xin unexpectedly produced mirabilite through the card system, which is a traditional Chinese medicine, a natural mineral, and an important raw material for manufacturing soda ash in the future.
China is the largest producer of mirabilite, natural mirabilite. The history of using mirabilite in China can be traced back to one or two thousand years ago. In pharmacies, mirabilite is also a very common traditional Chinese medicine, which can have a certain effect on diarrhea.
The natural mirabilite is generally sodium sulfate decahydrate, which can be turned into sodium sulfate only by slowly ventilating and dehydrating or heating to five or six degrees centigrade. In fact, sodium sulfate decahydrate and sodium sulfate have been lit up in pharmacies. The reason is simple. Some mirabilites have been stored for too long, and become sodium sulfate after dehydration, which saves the process of processing mirabilite.
Every step saved in chemical production will save a step and a lot of time. There is no problem in producing soda ash with high-purity sodium sulfate. Only high-purity sodium sulfate can produce soda ash of sufficient purity. Even if the purity of Lubeland process is not high, it is compared with other soda processes. The special nature of soda ash makes Lubeland process have many impurities, It can be removed by water washing and other simple methods, but it is just an additional step.
This is put on the industrial production, which is a bit cumbersome. Zhao Xin's card system skips the natural barrier of industrial products and laboratory products. As long as it can be lit up with the card system, it can be shown through the energy converted by money, which greatly saves time.
Perhaps this is a more advanced theory in the 32nd century. Under different scientific and technological systems, seemingly difficult things can be solved by countless methods.
With sodium sulfate, this is only the first step, which saves one step of Lubrand method. There are two remaining steps, which need not only more precise control, but also some other appliances. Fortunately, this is a very simple industrial soda process, and the requirements for equipment are not high. Miao Village, an ancient village, can meet the requirements, as long as there are iron and blacksmiths.
