CONTINUOUS METHOD FOR ALTERING THE MOLECULAR WEIGHT OF ORGANOSILICON COMPOSITIONS

摘要

A CONTINUOUS METHOD FOR ALTERING THE MOLECULAR WEIGHT OF ORGANOSILICON COMPOSITIONS A continuous method for altering the molecular weight of organosilicon compositions containing Si-bonded oxygen in the presence of a catalyst and preferably under decreased pressure, in which a cylindrical reactor is employed have a ratio of length to inside diameter of between 1:1 and 50:1. A reactive mixture is stirred in the cylindrical reactor by a stirring apparatus having one or more stirring blades, so that the mixture is subjected to a maximum centrifugal acceleration bmax of at least 70 m.s-2 and more preferably at least 165 m.s-2.
