ABSTRACT:
Organosilicon compounds of the general formula Iare produced by catalytically reacting silanes of the general formula IIwith alcohols of the general formula R′—OH, with the elimination of RIVOH, wherein the molar ratio of R—OH to RIVOH— groups is at least 1 and RIVOH is removed continuously or discontinuously from the reaction mixture. The organosilicon compounds may be used as coupling agents in filler-reinforced rubber mixtures.
