Abstract
Disclosed is a method for the production of silicon ester halides by the equilibration of chlorosilanes and silane esters. Organic phosphorous compounds are used as catalysts. These catalysts make it possible to obtain a virtually pure end product with a defined partial ester structure, and they reduce the formation of undesired by-products. The final distillation can also be performed in the presence of these catalysts without the occurrence of any disproportioning destruction of the reaction products.
