Abstract

The invention relates to a process for preparing vinylchlorosilanes by thermal non-catalyzed reaction of chlorosilanes with vinyl chloride at from 550 to 700.degree. C., using a ring-gap reactor which includes rapidly cooling the hot reaction gases after they have flowed through the ring-gap space, by quenching them with a liquid.
