1,1,1,3,5,5,5-Heptamethyltrisiloxane Chemical Properties,Usage,Production
Uses
Heptamethyltrisiloxane is used to catalyze reduction reactions in organic syntheses.
Description
Bis (trimethylsiloxy) methylsilane acts as an important raw material and intermediate used in organic synthesis, pharmaceutical and dyestuff. For example, it can be used for the platinum-catalyzed aromatic C-H silylation of arenes. It can also be used for the silylation of aryl iodides.
Chemical Properties
colourless liquid
Uses
1,1,1,3,5,5,5-Heptamethyltrisiloxane is a Basic material for synthetic polyalkyleneoxide modified heptamethyltrisiloxane which is a kind of specific structure surfactant for pesticide additives, coating additives, etc.
Uses
Bis(trimethylsiloxy)methylsilane is an important raw material and intermediate used in organic synthesis, pharmaceutical and dyestuff.
Uses
