Anwendungen
VerwendenDivinyl tetramethyl disiloxane could be used as a additives(intermediates) in the production process of addition silicone rubber, silicone gel, liquid silicone, vinyl silicone resin, vinyl silicone oil, platinum chromium compound and others. POTENTIAL VINYL NUCLEOPHILE IN CROSS-COUPLING REACTIONS. 1,3-Divinyltetramethyldisiloxane acts as a potential vinyl donor used in cross-coupling reactions. It is also involved in the copolymerization reaction with aromatic ketones.
Darstellung
synthetischeThe patent reports a method for preparing tetramethyldivinyldisiloxane, comprising the following steps: (1) mixing tetramethyldihydrogendisiloxane with a chloroplatinic acid catalyst to obtain a mixed solution; (2) bubbling acetylene into the mixed solution to carry out a hydrosilylation reaction, and after the reaction is completed, separating and purifying the reaction solution to obtain Divinyltetramethyldisiloxane.
