The main use of tris (ethoxy) borosilicate is not directly described in "Tiangong Kaiwu", but one or two of the ancient chemical methods can be deduced.
Borosilicate materials are strong and heat-resistant. In ancient glazing and ceramic firing techniques, there may be similar functions. In the production of glazed glass, if you want its texture to be crystal clear, heat-resistant and corrosion-resistant, you often need to add minerals to adjust its properties. If borosilicate at that time, it may help to increase the firmness of glazed glass, so that it will not deform under high temperature, and will not break if it is suddenly cooled and heated, so that glazed products can be widely used in utensils and decorations.
As for ceramics, borosilicate may be glazed. The glaze is applied to the surface of the ceramic body to increase its appearance and practicality. The addition of borosilicate may make the glaze surface more uniform and enhance its adhesion, making the ceramic durable and not easy to wear and peel off. Ancient ceramics are mostly used for daily use, such as bowls, bottles and cans. The glaze adjusted by borosilicate may make the ceramics last as new for a long time, and the color will not be reduced.
Furthermore, in ancient times, alchemy, pharmaceutical techniques, or borosilicate is also involved. Alchemists, who want to change gold and stone, often use various medicinal stones to refine. The characteristics of borosilicate may play a catalytic and stable role in it, helping alchemists to find their magic pills. In the same way as pharmaceuticals, the refining of some medicinal stones requires precise control of temperature and chemical changes, and borosilicate may be used at a specific stage to maintain the stability of the reaction environment and ensure the purity of the medicinal properties.
Although "Tiangong Kaiwu" does not specify three (ethoxy) borosilicate, it may have important uses in the fields of glazing, ceramics, alchemy and pharmaceuticals, etc., adding a lot of color to the refinement of various processes.

There are several ways to synthesize tribromoacetoxy bromobenzene. One method can also start with benzene. First, benzene and bromine are brominated under the action of an appropriate catalyst, such as iron filings or iron tribromide, to obtain bromobenzene. The key to this step is to control the temperature and the proportion of the material to ensure a smooth reaction and less side reactions.
After obtaining bromobenzene, let it react with an acetoxylating agent. Acetic anhydride can be used with an appropriate catalyst, such as sulfuric acid. In this reaction, the acetoxy group of acetic anhydride replaces the bromine atom on bromobenzene to obtain tribromoacetoxy bromobenzene. However, this process also requires attention to the reaction conditions, such as temperature, time, and the amount of catalyst, which are all related to the yield and purity of the product.
There is another method, which can first prepare benzene derivatives containing acetoxy groups, and then brominate. For example, phenol is used as the starting material to react with acetic anhydride to obtain phenyl acetate. This reaction is relatively easy and the yield is also good. Then, phenyl acetate is reacted with bromine, and brominated to introduce bromine atoms on the benzene ring. This bromination step requires fine-tuning the reaction conditions depending on the location and number of desired bromids. Due to the different electron cloud densities at different positions on the benzene ring, the difficulty and position selectivity of bromide are affected. Or by changing the catalyst or solvent, it can be promoted to selectively brominate and finally obtain tribromoacetoxybromobenzene.
Furthermore, the method of organic synthesis often varies due to factors such as the availability of raw materials, cost, difficulty of reaction and yield. In practice, when weighing the advantages and disadvantages, choose the most suitable method to obtain this compound efficiently and economically.

In today's market, the price of trihydroxyethyl propionamide varies according to various reasons. Looking at the quality of its advantages and disadvantages, the superior one is pure workmanship, stable and effective, and the price must be high; the inferior one is rough handyman, floating and inefficient, and the price is low. And the amount of production also depends on the price. If the product is abundant, the supply exceeds the demand, and the price tends to drop; if the product is thin, the supply exceeds the demand, and the price rises. And if there is a need in the market, if it needs to be prosperous, the merchant will bid for it, and the price may rise; if it needs to be weak, the stock will be large, and the price will often fall.
I have heard that the price of the best is as much as tens of gold per catty. It is widely used in various industries, including pharmaceuticals, dyeing and weaving. Depending on its good quality, it is not hesitant to buy it at a high price. And the inferior ones are only a few gold per catty, which is only used for rough work. The one pictured above is only cheap.
The distance of the place of origin is also the main reason. Those who are near the market will save freight, and the price will be slightly flat; those who are far away, the freight will be expensive, and the price will increase. And the business camp, its cost and its profit are all related to the price. If you want big profits, the price will be high; if you want quick sales, the price will be low.
To sum up, the market price of trihydroxyethylpropionamide cannot be covered in one word. All kinds of feelings are caused by phase errors, resulting in constant changes in its price. City people should carefully observe and measure it before they can obtain an appropriate price.

Tris (hydroxyethyl) acetamide is also a chemical. When storing and transporting, you need to pay attention to many matters.
First, when storing, you must choose a cool, dry and well-ventilated place. This is because it is afraid of moisture and heat. If it is in a high temperature and humid place, it may cause changes in properties or react with surrounding substances. For example, if it is an ancient treasure, choose a dry place to prevent mildew and decay. The same is true for this chemical.
Second, the storage place must be kept away from fire and heat sources. This chemical may be flammable, and in case of open flames and hot topics, it is dangerous to start a fire. Just like the ancients who were fireproof, isolating the fire source is the first thing.
Third, it should be stored separately from oxidants, acids, alkalis, etc., and must not be mixed. Due to the different properties of different chemicals, mixed storage can easily cause chemical reactions, or cause explosions and other serious consequences, just like different martial arts, strong fusion will be chaotic.
Fourth, when transporting, the packaging must be tight to prevent leakage. If it leaks outside, it will not only be wasted, but also cause harm to the environment and the human body. It is like a boat, and the hull can only move forward safely without leakage.
Fifth, during transportation, it should also be kept away from fire and heat sources, and the speed should not be too fast to avoid bumps. In this way, we can ensure the safety of chemicals during transportation, just like escorting precious materials in ancient times, and move forward cautiously to prevent accidents.
