二乙烯基四甲基二硅烷 - Introduction
Divinyltetryyldisilane (abbreviated as VTMS) is an organosilicon compound with the chemical formula CH3(CH3)3Si(CH2 = CH2)Si(CH3)3. The following is a description of its nature, use, preparation and safety information:
Nature:
divinyltethyldisilane is a colorless liquid with a special smell at room temperature. It is soluble in organic solvents and insoluble in water.
Use:
Divinyltethyldisilane has a wide range of uses in organic synthesis. It can be used as a component of materials such as crosslinking agent, plasticizer, modifier and adhesive, and is used to manufacture high-performance rubber, plastic, ink, adhesive, waterproof material, etc. In addition, it is also used in the preparation of packaging materials and surface coatings for electronic devices.
Method:
divinyltethyldisilane is typically prepared by reacting a silane derivative and a vinylation reagent. The specific method may be reacting trimethylchlorosilane with 1,2-dibromoethane, and then hydrolyzing and separating the product.
Safety Information:
divinyltethyldisilane is relatively stable under normal conditions of use. However, it is combustible and contact with strong oxidants should be avoided. During operation, appropriate personal protective measures should be taken, such as wearing chemical protective glasses, gloves and protective clothing. In case of contact with skin or eyes, rinse immediately with plenty of water. If necessary, seek medical assistance.
