Abstract
The present invention relates to a process for preparing organosilicon compounds which contain at least one H.sub.2 C.dbd.CH--Si-group, by reacting an organosilicon compound which contains at least one H--Si-group with acetylene in a gas/liquid phase in the presence of at least one addition catalyst and extracting the organosilicon compound which contains at least one H.sub.2 C.dbd.H--Si-group from the reaction mixture, wherein an organosilicon compound which contains at least one H--Si-group, the acetylene, which is used in stoichiometric excess, and a substantially inert liquid phase is brought into very intimate contact in a jet tube loop reactor in the presence of a catalyst, and the organosilicon compound which contains at least one H.sub.2 C.dbd.CH--Si-group is subsequently extracted from the reaction mixture and the excess acetylene is recycled into the process.
