The present invention relates to a process for the preparation of organosilicon compounds which contain at least one H 2 C = 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 recovery of the silicon-organic compound which contains at least one H 2 C = CH-Si group from the reaction mixture, which is characterized in that an organic silicon compound which contains at least one H-Si group, the acetylene, which is used in excess, and a largely inert liquid phase in a jet nozzle loop reactor in the presence of a catalyst intimately brings together and the silicon-organic compound, the at least one H 2 C = CH-Si Contains group, then wins from the reaction mixture and returns the excess acetylene to the process. |
