1-Octanesulfonic Acid, 3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluoro-

This is a question about borax. Borax, chemically called sodium tetraborate, has unique properties. Looking at its physical properties, it is normally a colorless translucent crystal, or a white crystalline powder, which is quite shiny and soft in texture. Its taste is salty and can be slowly weathered in air.
As for its chemical properties, borax is alkaline to a certain extent. When exposed to acid, it will react and form boric acid. Its hydrolysis is also worthy of attention. It can be hydrolyzed in water to make the solution alkaline. Under heating conditions, borax will gradually lose its crystalline water and melt into a glassy substance. Due to its structure containing boron-oxygen bonds, borax is widely used in many fields. In the industrial field, it is often used as a detergent, water softener, etc.; in chemical production, it is an important raw material for the preparation of other boron compounds; in medicine, it has also been used for disinfection and anti-corrosion, but now due to safety considerations, the application is limited.
Although borax has many uses, it is necessary to pay attention to its toxicity. Excessive intake of borax can endanger human health and affect the normal functions of the digestive system and nervous system. Therefore, when using borax, it is necessary to strictly follow safety regulations and relevant standards, and must not be negligent to avoid adverse consequences.

1 - Dace dried, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8 - Thirteen Oceans - its main use, although not described in detail in the ancient book "Tiangong Kaiwu", but according to common sense and traditional application inferred, or have the following ends.
First, the way to eat. Dace dried by a specific process, after the meat is dehydrated, the flavor is unique, the taste is firm, and the taste is rich. It can be eaten directly after cooking to taste its salty and mellow taste, and can also be used as an ingredient to serve with various matching dishes, such as stir-frying with vegetables, which can add a rich taste and salty flavor to the dishes and add a lot of color to the table.
Second, it is convenient for storage. In the past, when fresh-keeping means were scarce, the dace was made, which greatly extended its shelf life. In this way, when the fish were abundant, part of the dace could be preserved in the sun for future consumption when there were no fish to catch or ingredients were in short supply, becoming an important way to ensure the stability of food supply.
Third, for trade. The dace produced by Thirteen Oceans, with its unique quality, may become a characteristic commodity in trade exchanges. Circulating along trade routes to various places can not only bring economic benefits to the local area and promote the exchange of materials between regions, but also make this unique product famous and promote the exchange and integration of food cultures between different regions.

To prepare "1-glycyrrhizic acid, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 8-tridecene", the method is as follows:
Prepare all the things you need first, glycyrrhizic acid should be refined, and the materials of various olefins should also be selected for their purity. In a clean kettle, bake it over a warm fire to remove its moisture. When the kettle is cool, add naglycyrrhizic acid to it, slowly inject an appropriate amount of solvent, stir to mix well. The choice of this solvent is a matter of success or failure, and it should be considered according to the physical properties.
Then, control its temperature in a delicate way, and raise the temperature slowly. When it reaches a suitable temperature, slowly add various olefinic reactants. When adding, do not be impatient, it must be uniform and slow to prevent it from changing. Add it, adjust its temperature, keep it constant temperature, and keep stirring, so that all things are fully miscible.
In the meantime, when observing its changes with a keen eye, observe its color, smell its gas, and measure its quality with secret techniques in a timely manner. If the temperature is high, drop it; if the temperature is low, rise it, so that the temperature is constant and should be stable.
Wait for it to be finished, filter it with a fine filter to remove its insoluble matter. Then use the method of distillation to remove its solvent and keep its essence. Compound with various purification techniques, such as chromatography, recrystallization, etc., refine the quality, remove the impurities, and finally obtain pure "1-glycyrrhizic acid, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 8-tridecene".
However, this process requires the operator to have exquisite skills and a calm heart. If you are not careful, you will lose all your previous efforts, so you should be cautious.

When using it, you need to pay attention to the following things:
First, check its quality. There are many categories in the market, and the quality is also uneven. Choose the time to choose the one with uniform luster, pure and no odor. Looking at its packaging, it needs to be well sealed, without leakage or dampness, so as to ensure its mellow taste and complete medicinal effect.
Second, control its usage.
Third, strong, its nature is warm, and the dosage should be determined according to the amount of food and the taste of the individual. When cooking vegetarian food, the amount should be small to prevent the taste from masking its original taste; when making food, it can be slightly increased to remove the smell and increase its taste. If the amount is not used properly, more will taste and damage the charm of the dish; less will be less, and it will be difficult to achieve the expected effect.
Furthermore, know the timing. Adding ten or three ounces at different cooking stages has different effects. When stewing and cooking, the ingredients can be placed at the beginning, so that the taste can be slowly penetrated into the food; when frying and frying, it is advisable to put it in the middle and early stages, and take advantage of the oil temperature to stimulate it. However, when frying, it is generally enough to use three ounces of flavor before frying. When frying, it is easy to add ingredients that can cause charred paste, which will damage the taste and shape.
Those who avoid conflict. The ingredients are diverse and may not be suitable for some food materials. For example, when used with hot and dry food materials such as chili peppers, garlic, etc., it may cause overheating in the body, sores, and throat swelling and pain. Therefore, when matching food materials, when its flavor is clear, it should be avoided.
The last one should be properly preserved.
Contains volatile oils and other ingredients, which are easy to evaporate and dissipate. When used, it should be placed in a dry, cool and dark place away from light, sealed and stored to prevent the spread and moisture deterioration, so as to prolong its use and ensure its quality as before.

What Guan Jun is asking is about "the market price of 1-loach oxalic acid, 3,3,4,4,5,5,6,6,7,7,8,8-tridecane-". I have never heard of this" 1-loach oxalic acid "being priced in the market, or it is an extremely rare and newly developed chemical, or the name is wrong, and it is difficult for ordinary people to know its exact market price.
As for" 3, 3, 4, 5, 5, 6, 7, 7, 8, 8, 8-tridecane ", the market price of such chemicals depends on many factors. Its purity is one of the key factors. If the purity is extremely high, it is suitable for precision chemical experiments, high-end material synthesis and other fields, and its price will be high; if the purity is slightly lower, it is mostly used for general industrial production assistance and other purposes, and the price is relatively low.
Furthermore, the market supply and demand relationship also affects its price. If this tridecane is in high demand in many industries at a certain period, but the supply is limited, the so-called "rare is expensive", its price will rise; on the contrary, if the supply exceeds the demand, the merchant will reduce the price in order to get rid of it.
In addition, the production process, raw material costs, etc. also affect its price. Complex and expensive production processes will inevitably lead to higher product prices; if raw materials are easily available and inexpensive, the product price may be affordable. However, it is difficult to determine the exact market price without knowing the current specific market conditions and the exact status of various factors.
