(Triethoxy) borosilicate anhydride, its main use is not detailed in the genus of "Tiangong Kaiwu", but it is deduced from today's knowledge, or it may have various wonderful uses.
The concept of silicone boronic anhydride is such a thing, although there is no detailed record in ancient times, but in today's world, (triethoxy) borosilicate anhydride is often used in chemical industries. First, in the field of materials, it can be used as a modifying agent. Because of its unique structure, it is introduced into the material, which can improve its performance. If added to some polymeric materials, it can increase its mechanical strength, making it stronger and tougher, just like the craftsmen of ancient times used clever techniques to strengthen utensils, making it durable.
Furthermore, in the paint industry, (triethoxy) boronic anhydride also has extraordinary power. It can be used as an additive for coatings to improve the adhesion of coatings, making it stick firmly to the device like paint, and it is not easy to peel off. And it can improve the weather resistance of coatings. After wind and rain, hot sun and cold, it can still maintain its color and protective effect, just like a layer of strong and durable armor for utensils.
In some catalytic reaction systems, it can be used as a co-catalyst. It can adjust the activity and selectivity of the main catalyst, so that the reaction is like a boat traveling in water, moving along the flow, efficiently and accurately generating the required products, saving materials and time, just like a convenient path for chemical reactions.
Although "Tiangong Kaiwu" did not describe the use of this (triethoxy) boronic anhydride in detail at that time, today, it has shown important capabilities in many fields, adding power to work, materials, and chemicals, which is a must-see in chemical materials.

(Tri-acetoxy) silicic acid, its physical properties are as follows:
This compound is often in the form of a powder, and the ground is dry. If there is a new snow in winter, it will feel slippery. Its color is white like white, and it can be plain.
In terms of solubility, in normal water, (three-acetoxy) silicic acid can be slowly dissolved, just like spring snow when it is warm, and it melts in water, so that the water is slightly low. Then mix the tablets, and the energy is uniformly dispersed to form a fixed solution. In water, its dissolution rate is accelerated, as if it fell quickly, and it is instantly integrated into the water, and the solution is more clear and transparent.
The density of the powder is slightly larger than that of the ordinary powder. When placed in the palm of your hand, you can feel a certain weight, not like a flocculent.
In addition, (triacetoxy) silicic acid has a certain degree of absorption. If exposed to air, it will absorb water like dry and thirsty soil for a long time, and the powder will absorb water in the air. The powder will have a slight agglomeration image, just like sand and moisture.
In terms of melting, it needs to reach a specific high temperature in order to make it solid and flow like a liquid. This high temperature is like the fire of gold, and it will be transformed into its shape. In the general environment, (triacetoxy) silica can maintain its stability, maintain its own shape, and is not easy to modify.

(Tribasic) silicic acid, also known as water glass, is a kind of chemical compound, and its properties are very special. Its properties are as follows:
- ** Physical properties: It is often transparent or light-colored viscous liquid, and the appearance is similar. This viscous property is due to the strong interaction of molecules. Its viscosity is affected by about 60 degrees. The higher the degree and the lower the degree, the greater the viscosity. Solidified by light or gray glass, it is glassy and brittle.
- ** Chemistry properties: First, its aqueous solution is high-quality, and oxy seeds are produced due to the hydrolysis of silicate seeds. This property makes it possible to generate acid and generate silicic acid. In case of acid, it quickly reacts and precipitates silicic acid, and the reverse formula is $Na_2SiO_3 + 2HCl = 2NaCl + H_2SiO_3. Furthermore, it has strong adhesion and can bond tightly to the surface of multiple substances. The reason is that silicate can form gold particles or groups on the surface of the substance, so it is often used as a bonding agent. It is used in the field of building materials to bond stone, glass and other materials. In addition, it can decompose and react with many metals, and some gold solutions can react to generate silicate deposits. For example, the chlorination solution reacts to generate silica white deposits, and the reverse formula is $Na_2SiO_3 + CaCl_2 = CaSiO_3? + 2NaCl $. In the air, carbon dioxide is slowly reversed to generate carbonated silicic acid, which causes it to remain in the air for a long time. The reverse formula is $Na_2SiO_3 + CO_2 + H_2O = Na_2CO_3 + H_2SiO_3.

There are various ways to synthesize trichloroacetoxy silane, which I will describe in detail today.
One of the methods can be obtained by reacting silane with trichloroacetyl chloride under appropriate conditions. This reaction requires careful temperature control and the selection of a suitable catalyst to make the reaction proceed smoothly. The activity of silane is very different. When encountering trichloroacetyl chloride, the chemical bonds of the two are rearranged and combined to form trichloroacetoxy silane. For example, in an organic solvent, a metal salt is used as a catalyst to maintain a certain temperature range. The two interact and go through a complex chemical process. Then the target product is formed.
In the second method, the compound containing silicon is used as the starting material, and the functional group is first converted to introduce a group that can react with trichloroacetyl groups. For example, the silica alcohol compound is activated by a specific reaction, and then reacts with trichloroacetic anhydride. The acyl group of trichloroacetic anhydride is active and can be combined with the activated hydroxyl group to remove the corresponding by-products, thereby preparing trichloroacetoxysilane. In this process, the pH of the reaction environment and the reaction time are strictly required. A slight difference will affect the purity and yield of the product.
Another method starts from silicon halide. The silicon halide reacts with a nucleophilic reagent, introducing an oxygen-containing group, and then reacts with a trichloroacetyl source. The halogen atom in the silicon halide is active and easily replaced by a nucleophilic reagent. When combining with the trichloroacetyl group later, it is necessary to pay attention to the selectivity of the reaction. The purpose of increasing the amount of target product can be achieved by adjusting the ratio of reaction solvent and reactant.
All these synthesis methods have their own advantages and disadvantages. It is necessary to choose carefully according to the actual needs, considering the availability of raw materials, the level of cost, and the requirements of product purity, etc., in order to obtain a suitable synthesis path to prepare trichloroacetoxy silane.

Zirconium (trihydroxyethyl) silicate is a valuable chemical raw material. When storing and transporting, many aspects need to be paid attention to.
Let's talk about storage first. First, you must find a dry place. Because it is afraid of moisture, if it is in a humid place, it is easy to react with water vapor and cause quality deterioration. For example, during the rainy season in the south, the air humidity is high, and it needs to be tightly sealed with moisture-proof materials, and the warehouse should have dehumidification equipment. Second, the temperature should also be well controlled. Do not place it in a high temperature place to prevent its chemical structure from changing due to heat. Generally, it should be stored in a cool place, and the temperature should not exceed 30 degrees Celsius. Third, it must be separated from other things. Chemicals such as acids and alkalis come into contact with or react chemically with them, so they should be stored separately and marked well.
Let's talk about transportation. The first heavy packaging is sturdy. Special containers are required to ensure that they are not damaged during bumps and collisions. If long-distance land transportation, the road conditions are complicated, and the packaging is not strong and easy to leak. Second, the means of transportation should be clean. Other chemicals remain in the car, or stain (trihydroxyethyl) zirconium silicate. Third, follow the transportation regulations. Because it is a special chemical, the transportation qualification, route, time, etc. have strict requirements. Practitioners must be familiar with and abide by it, and must not operate in violation of regulations to avoid disasters. Only careful storage and transportation can ensure the quality and safety of (trihydroxyethyl) zirconium silicate.
