Its density is about 0.965 - 0.975g/cm ³, and the density value is related to its distribution and mixing in different media. For example, when preparing composites, the density affects the uniform mixing degree of 3-aminoethoxy triethoxy silane with other materials, which in turn affects the overall properties of the material.
Furthermore, its flash point is about 110 ° C. The flash point indicates that this compound is dangerous in case of open flame and high heat can cause combustion and explosion. During storage and use, it is necessary to strictly control the ambient temperature and keep it away from ignition sources to ensure safe operation.
In terms of solubility, 3-aminoethoxy triethoxy silane is soluble in alcohols, ketones, esters, aromatics and other organic solvents. This good solubility allows it to be used as a coupling agent to effectively improve the interfacial bonding force between inorganic and organic matter.

What is the production method of 3-methoxytrifluorotoluene?
3-Aminoethoxyltriethoxysilane is a kind of organosilicon compound. Although the preparation method is not directly described in the ancient book "Tiangong Kaiwu", it can be deduced from similar chemical process ideas.
To prepare 3-aminoethoxyltriethoxysilane, it is often obtained by a series of reactions between silicon-containing raw materials and amino-containing raw materials. Initially, a suitable silane, such as trichlorosilane, is reacted with ethanol under appropriate conditions. This reaction requires the substitution of chlorine atoms in trichlorosilane with the hydroxyl group of ethanol under the action of a specific temperature and catalyst to form triethoxysilane. The reaction is roughly as follows:
$SiHCl_ {3} + 3C_ {2} H_ {5} OH\ stackrel {catalyst} {\ longrightarrow} Si (OC_ {2} H_ {5}) _ {3} + 3HCl $
Then, the amino-containing compound is introduced. Taking 2-aminoethanol as an example, 2-aminoethanol is reacted with the triethoxysilane obtained above. This process also requires a suitable temperature and catalyst assistance to make the hydroxyl group of 2-aminoethanol react with the siloxy bond of triethoxysilane to achieve the access of aminoethoxy, and finally 3-aminoethoxysilane is obtained. This step of the reaction is as follows:
$Si (OC_ {2} H_ {5}) _ {3} + HOCH_ {2} CH_ {2} NH_ {2}\ stackrel {catalyst} {\ longrightarrow} Si (OC_ {2} H_ {5}) _ {3} OCH_ {2} CH_ {2} NH_ {2} $
When preparing, the reaction temperature, raw material ratio, catalyst selection and dosage must be precisely controlled. If the temperature is too high or too low, the reaction rate may be improper and the product is impure; the raw material ratio is unbalanced or the reaction is incomplete; if the catalyst is selected incorrectly or the dosage is deviated, the reaction process and product quality will also be affected. In this way, through fine operation and regulation, relatively pure 3-aminoethoxy triethoxy silane can be obtained.
What are the precautions for storing and transporting 3-methoxytrifluorotoluene?
3-Aminoethoxyltriethoxysilane is used in storage and transportation, and many precautions need to be paid attention to.
When storing, the first environment is heavy. This substance should be stored in a cool, dry and well-ventilated place. If the environment is humid, moisture can easily react with silane, causing it to deteriorate and fail. And the temperature should also be appropriate. Excessive temperature will accelerate its chemical reaction rate, or cause adverse phenomena such as decomposition, so it is necessary to keep away from heat sources and ignition sources to prevent accidents. At the same time, it should be stored separately from oxidants, acids, etc. Because of its active chemical properties, it is easy to react violently in contact with these substances, endangering storage safety.
Furthermore, storage containers are also exquisite. Be sure to choose a well-sealed container to prevent it from evaporating and coming into contact with moisture, oxygen and other components in the air. The material of the container used must have good compatibility with the substance and will not chemically react with it. For example, suitable glass bottles or plastic drums of specific materials can be selected.
During transportation, the packaging must be stable and reliable to ensure that the packaging will not be damaged due to bumps, collisions, etc. during transportation, which will lead to leakage. Transportation vehicles need to be equipped with corresponding emergency treatment equipment and protective equipment for emergencies. Transport personnel should also be familiar with the characteristics of the substance and emergency treatment methods. If there is a leak on the way, they can respond quickly and correctly. In addition, the transportation process needs to strictly follow the relevant regulations on the transportation of hazardous chemicals, and complete transportation procedures to ensure the legal compliance, safety and order of transportation. In short, whether it is storing or transporting 3-aminoethoxyltriethoxysilane, it must be treated with caution and must not be negligent to ensure the safety of personnel and the environment is not endangered.
