Hexamethylcyclotrisiloxane Chemical Properties,Usage,Production
Chemical Properties
White crystalline solid
Physical properties
mp 64–64.5 °C; bp 133–134 °C.
Uses
Hexamethylcyclotrisiloxane is used in the preparation of graft polymers and block polymers. It is also a useful biochemical for proteomics research and also acts as an intermediate in organic reactions.
Uses
Hexamethylcyclotrisiloxane can be used as reagent for the preparation of dimethylsilanols, trapping of insitu- generated silanones, silylenes, silyl azides, silanethiones, and derivatives. Hexamethylcyclotrisiloxane, (D3) is the simplest member of a series of cyclic oligodimethylsiloxanes, primarily used as synthetic equivalents for the reactive intermediate dimethylsilanone. This characteristic is responsible for its extensive application in polymer chemistry. Hexamethylcyclotrisiloxane has also been exploited as an efficient trapping reagent for a variety of shortlived intermediates, including silanones and silyenes. The ability of D3 to intercept these reactive species has been attributed to its rigid, planar structure,8 and the resultant release of strain from ring expansion.
Uses
Hexamethylcyclotrisiloxane, is the simplest member of a series of cyclic oligodimethylsiloxanes, primarily used as synthetic equivalents for the reactive interme- diate dimethylsilanone. It is one of the main raw materials for silicone products. It is widely used in aviation, military industry, medicine and petrochemicals etc.
- Hexamethylcyclotrisiloxane undergoes ring-opening anionic polymerization reactions, suggesting use in polymer synthesis. It is also suggested for the treatment of powders and fillers to render them hydrophobic.
- Hexamethylcyclotrisiloxane mainly used for products of methyl vinyl silicone rubber. It’s also the important raw materials for synthesizing other high polymers.
- It may be used as an effective trapping reagent for a variety of short-lived intermediates, including silanones and silyenes.
- Hexamethylcyclotrisiloxane has many unique characteristics.The reaction of It is more active, can be easily and quickly polymerized under lower temperature and simple catalysts.
- may be used to synthesize many kinds of organic silicone products, which have better stability, better insulation properties and better water resistance.
- may be used to synthesize silicon rubber, which may has better elasticity, better abrasive resistance, and better corrosive resistance.
- may be used to synthesize silicone oil, which may has lower freezing point and less surface tension, it is slightly affected by temperature.
- Hexamethylcyclotrisiloxane is flammable. Use and store with all precautions required for Flammable Materials. Care should be exercised in handling GP-685 to prevent contact with skin or eyes. Wear safety glasses with side shields and rubber gloves when handling.
Definition
ChEBI: Hexamethylcyclotrisiloxane is an organosilicon compound.
