ABSTRACT:
A process for continuously preparing compounds containing SiOC groups, in which chlorosilane(s) are partially reacted with alcohol and optionally also with water in a prereactor, and the partial reaction product therefrom is fed to a first reaction unit comprising a column, reacted with alcohol and optionally water to give a crude product which still comprises volatile constituents, and the crude product is transferred to a second reaction unit comprising a column in which alcohol is additionally introduced, and freed there of volatile constituents, optionally in the presence of an unreactive organic solvent, the desired end product being removed at the lower end of the second reaction unit.
