Process for the production of condensation products or organosilicon compounds having at least one silicon-bonded hydroxyl group. The process comprises contacting the organo-silicon compound with a quaternary ammonium borate, -phosphate, -carbonate or -silicate. May be employed for example for the polymerisation of α,w silanol-terminated polydiorganosiloxanes and for the production of organosiloxanes having organo-functional e.g. aminoalkyl groups.
具有至少一个硅键羟基的缩合产物或有机硅化合物的生产工艺。该工艺包括将有机硅化合物与硼酸季铵、磷酸季铵、碳酸季铵或硅酸季铵接触。例如,可用于α,w 硅烷醇端聚二有机硅氧烷的聚合以及具有有机官能团(如氨基烷基)的有机硅氧烷的生产。
