Abstract

Continuous hydrosilylation of compounds (A) bearing C—C multiple bonds by means of silicon compounds (B) having Si—H groups, in which the reaction components (A) and (B) are reacted continuously in an integrated loop-tube reactor, with reaction mixture being conveyed from the tube into the loop and back again so that a section of the tube is part of the loop circuit, provides a highly controllable reaction process with high product yields.
