Abstract:
A process comprising:(a) feeding continuously a hydrosilatable olefin and a hydrosilane or hydrosiloxane capable of reacting with the olefin into a reactor;(b) reacting said olefin with said hydrosilane or hydrosiloxane in the reactor in the presence of a catalytically effective amount of catalyst to form a hydrosilated product;(c) withdrawing continuously from said reactor a crude product stream,(d) separating said crude product stream in a purifier to produce(i) a recycle stream comprising unreacted olefin, or unreacted hydrosilane or hydrosiloxane, and(ii) a product stream comprising said hydrosilated product; and(e) recycling said recycle stream (d)(i) into said reactor; and wherein the conversion of the stoichimetrically limiting reactant in the reactor is greater than 80%.
