1,5-Divinylhexamethyltrisiloxane - Introduction

1,5-Divinylhexamethyltrisiloxane, chemical formula C14H32O3Si3, also known as Vinyltrimethylsilane, is an organosilicon compound.

Nature:
1,5-divinylhexamethyltrisiloxane is a colorless liquid with a special smell. It has a low surface tension and a high degree of synergy, and plays an auxiliary and media role in organic synthesis. It is a flammable liquid that can form an explosive mixture with oxygen and must avoid contact with ignition sources.

Use:
1,5-divinyl hexamethyltrisiloxane is mainly used for the synthesis of various organic silicon compounds, such as silane coupling agents, silane polymers, silane surfactants, etc. It can be used as an active reagent and reaction medium in organic synthesis, and can be used to catalyze platinum catalysts and olefin polymerization reactions. In addition, it can also be used as a binder, additive and lubricant.

Preparation Method:
The preparation method of 1,5-divinyl hexamethyltrisiloxane is generally synthesized by vinyl reaction. The specific method is to react triethylchlorosilane and vinyl chloride under alkaline conditions to first produce 1,5-divinylhexamethyltriethylsiloxane, which is then converted to 1,5-divinylhexamethyltrisiloxane by acid catalysis.

Safety Information:
1,5-divinyl hexamethyltrisiloxane has low toxicity, but is a flammable liquid, need to avoid contact with oxygen, fire and high temperature. During use, attention should be paid to protective measures, such as wearing appropriate personal protective equipment and ensuring a well-ventilated working environment. Relevant safety regulations and operating procedures shall be observed during handling and storage.
