4- (triethoxy) ethyl silicate, also known as ethyl orthosilicate, its main uses are as follows:
First, in the field of coatings, ethyl orthosilicate plays a significant role. It can be used as an additive for coatings, which helps to improve the hardness, wear resistance and chemical corrosion resistance of coatings. Because it can react with other components in the coating to form a tough and stable network structure, thereby enhancing the protective performance of coatings. For example, in the anti-corrosion coatings of some industrial equipment, the addition of ethyl orthosilicate can effectively prolong the time of equipment to resist external erosion and ensure the normal operation of equipment.
Second, in terms of adhesives, ethyl orthosilicate plays an important role. It can be used as a crosslinking agent for adhesives to enhance the chemical bonding between the adhesive and the surface of the bonded material and improve the bonding strength. In some occasions that require high bonding strength, such as the bonding of ceramics and metals, the use of adhesives containing ethyl orthosilicate can ensure that the two are firmly bonded and not easy to separate.
Third, ethyl orthosilicate is a key raw material in the preparation of organic-inorganic hybrid materials. Through appropriate processes, it can be combined with organic polymers to prepare hybrid materials with the advantages of both flexibility of organic materials and rigidity and thermal stability of inorganic materials. These hybrid materials are widely used in the fields of optics, electronics, etc., for example, for the preparation of high-performance optical lenses, which have not only good light transmittance, but also high hardness and scratch resistance.
Fourth, in the preparation of catalyst support, ethyl orthosilicate is also very useful. It can form a silica support with a porous structure through hydrolysis polycondensation reaction, which can support various active components, such as metal catalysts. Due to its porous structure providing a large specific surface area, it is conducive to the dispersion of active components and the adsorption and diffusion of reactants, thereby improving the activity and selectivity of the catalyst.
In addition, ethyl orthosilicate is a commonly used precursor in the preparation of nano-silica. By controlling its hydrolysis and polycondensation processes, nano-silica particles with uniform particle size and good dispersion can be prepared. These nano-silica are used as reinforcing agents in rubber, plastics and other industries, which can significantly improve the mechanical properties of materials.

4- (trihydroxymethyl) aminomethanesulfonic acid, also known as TES, is a commonly used reagent in biochemical research. Its physical properties are as follows:
From the perspective of this substance, it is a white crystalline powder, like a fine snow, with a uniform and delicate texture. It shimmers under the light, as if it contains endless mysteries. Smell it, it is almost odorless, just like a pool of quiet water, without pungent or special breath, giving people a sense of purity.
Its melting point is quite high, between 224 and 229 degrees Celsius. Such a high melting point is like a strong fortress, requiring a considerable amount of energy to break its lattice structure and convert it from a solid state to a liquid state. This property allows it to maintain a stable solid state at room temperature, making it easy to store and transport.
In terms of solubility, it is easily soluble in water. When it meets water, it is like a smart fish entering the vast sea, rapidly dispersing and dissolving to form a uniform solution. However, in organic solvents, such as common ethanol, ether, etc., its solubility is poor, just like refusing organic solvents thousands of miles away, only loving water as a medium. This solubility characteristic determines that it participates in reactions in the form of aqueous solutions in biochemical experiments, providing a stable environment for many biochemical reactions.
In addition, the substance has a certain degree of hygroscopicity. In humid air, it is like a dry sponge that quietly absorbs surrounding water vapor, which may affect its own purity and performance. Therefore, when storing, it needs to be placed in a dry place to prevent it from deteriorating due to moisture absorption. Although this physical property is subtle, it is of great significance to its experimental application and preservation. A little carelessness may affect the accuracy and reliability of the experiment.

There are several methods for synthesizing 4- (triethoxy) benzoic acid:
First, benzoic acid is used as the starting material, and halogen atoms are introduced into the benzene ring after a halogenation reaction. This halogenation reaction, often using liquid bromine or iron halide as a catalyst, is heated in a suitable solvent to obtain halogenated benzoic acid. Subsequently, the halogenated benzoic acid is reacted with triethoxysilane under alkaline conditions in a polar aprotic solvent such as N, N-dimethylformamide. The basic reagent can be selected from potassium carbonate, etc., and the nucleophilic substitution reaction can produce 4- (triethoxy) benzoic acid.
Second, starting from benzaldehyde, the formyl group is introduced into the para-position of the formyl group on the benzene ring through the Wilsmeier-Hacker reaction to form p-formylbenzoic acid. Then, p-formylbenzoic acid is reduced to p-hydroxymethylbenzoic acid, and reducing agents such as sodium borohydride can be used. Subsequently, p-hydroxymethylbenzoic acid and triethoxysilane are etherified under acid catalysis. The commonly used acid is p-toluenesulfonic acid, which is refluxed in water-carrying agents such as toluene, and the final product 4 - (triethoxy) benzoic acid is synthesized.
Third, using benzene as raw material, first through Fu-Ke acylation reaction, using Lewis acid such as aluminum trichloride as catalyst, and acid chloride containing carboxyl group and ethoxy group related structures, the corresponding substituent is directly introduced on the benzene ring, and the 4- (triethoxy) benzoic acid structure is constructed in one step. This reaction requires precise control of the reaction conditions to ensure the selectivity of the acylation position in order to obtain the target product efficiently.

When storing and transporting (triethoxy) silicic acid, there are many key points to pay attention to.
First, the storage place must be cool and dry. This is because the substance is prone to react with water vapor in a humid and warm environment, resulting in changes in its performance. If the humidity at the storage place is too high, the moisture may interact with the ethoxy group in the silicic acid, causing a hydrolysis reaction to form products such as silicic acid gels, which will adversely affect its quality and use effect.
Second, ensure that the storage and transportation containers are well sealed. Sealing not only prevents the intrusion of external water vapor, but also prevents the substance from evaporating and escaping. If the container is not well sealed and the silicic acid evaporates into the air, it will cause material loss on the one hand, and harm the surrounding environment and human health on the other hand, because it is irritating to a certain extent.
Third, keep away from fire sources and strong oxidants during storage and transportation. (Triethoxy) silicic acid is a silicone compound. Although it is not a highly flammable substance, it still poses a risk of combustion in case of open flames and hot topics. Strong oxidants may react violently with it, resulting in dangerous conditions.
Fourth, handle with care when handling. Due to the fact that most of the packaging containers are made of glass or fragile materials, if they are violently collided or dropped during handling, the containers are easily damaged, resulting in silicic acid leakage, which not only causes material waste, but also makes it difficult to clean up the leaks, and the leaked substances may cause pollution to the environment.
In short, the storage and transportation of (triethoxy) silicic acid requires careful and thorough operation, and strict compliance with relevant specifications and requirements, so as to ensure its quality and safety.

Wen Jun's inquiry is related to the market price of (triethoxy) silane acetic acid. This product is in the market, and its price changes depend on multiple reasons.
First, the price of raw materials is the main factor. If the price of all the raw materials required for its preparation is high and difficult to find, then the price of (triethoxy) silane acetic acid will rise accordingly. Covering the cost of raw materials accounts for the weight of its cost, the price of raw materials moves, and the price of finished products is also difficult.
Second, the simplicity of the process also has an impact. If the method of preparation is complicated and expensive, requires high-tech techniques, skilled workmanship, or energy consumption is very large, the cost will be high, and the market price will not be low.
Third, the state of supply and demand determines its price. If the market demand for this product is strong and insufficient, and there are few suppliers, the price will rise; on the contrary, if the supply exceeds the demand, merchants will reduce the price to sell their goods.
Fourth, changes in the current situation are also relevant. Tax adjustments, policy changes, and trade regulations can all affect the price. If the tax increases, the cost of the merchant increases, and it must be transferred to the selling price; the policy encourages production, the supply increases, and the price may drop.
As for the current market price, it is difficult to determine. Cover the ever-changing market, and information is fleeting. To know the exact price, it is advisable to consult the merchant of chemical materials, or visit the platform of chemical trading, to know its recent price. And different quality, different quantity, the price is also different. If you want to know more, you must study it carefully.
