Vinyltriacetoxysilane need to pay attention to when storing
Vinyl triacetoxysilane should be stored with caution. This is an organosilicon compound with active chemical properties, so the method of storage is related to its quality and safety.
First, pay attention to the storage temperature. It should be placed in a cool place to avoid high temperature baking. High temperature can accelerate its chemical reaction, or cause the risk of deterioration. Therefore, the warehouse temperature should be controlled in a moderate range, such as between 5 ° C and 25 ° C, in case the temperature is too high, causing changes in acetoxy groups and damaging its chemical properties.
Second, humidity is also the key. This substance is prone to hydrolysis in contact with water, causing its structure to be broken and its efficacy to be greatly reduced. It is to be stored in a place that must be kept dry. A desiccant can be placed next to it to absorb moisture and keep the environment dry and moisture-free.
Third, the choice of container should not be ignored. Corrosion-resistant containers should be selected, such as glass or specific plastic materials. Because its acetoxy group is corrosive to a certain extent, if the container is not resistant, there is a risk of leakage, and it reacts with the container material to contaminate its body.
Fourth, it is also important to avoid light. Light or photochemical reactions can affect performance. Therefore, for storage, it is better to choose a dark place, or cover the container with a light-shielding material to protect it from light interference.
Fifth, isolated storage is also necessary. Do not coexist with strong oxidizing agents, strong bases and other substances in the same room. Due to its active chemical properties, encounters with them, or violent reactions, endanger safety.
Storage of vinyl triacetoxysilane requires thorough consideration in terms of temperature, humidity, container, light, and isolation, and careful care to ensure its quality for subsequent use.

Vinylsilanol is slowly added to the reaction vessel containing acetic anhydride, and a catalyst such as concentrated sulfuric acid or p-toluenesulfonic acid is also added. The reaction temperature should be maintained at 40 to 60 degrees Celsius. During this process, the hydroxyl group of silanol and the acetyl group of acetic anhydride undergo esterification reaction to form the target product vinyltriacetoxysilane. After the reaction, through neutralization, extraction, distillation and other steps to remove impurities and obtain a high-purity product.
Third, the transesterification reaction is carried out with vinyltrimethoxysilane and acetic acid. In the reaction system, an appropriate amount of catalyst, such as titanate, is added. When heated to 80 to 100 degrees Celsius, the methoxy group of vinyltrimethoxysilane and the carboxyl group of acetic acid are transesterified to produce vinyltriacetoxysilane and methanol. Subsequent operations such as separating methanol and refining products result in qualified products. Each method has its own advantages and disadvantages. In practical application, it is necessary to comprehensively consider factors such as raw material availability, cost, and product purity requirements to choose the most suitable method.
