A process for preparing epoxysilanes by reacting a hydrogensilane with an allyl glycidyl ether in the presence of a catalyst and working up the crude product obtained, where the catalyst is removed from the crude product and the crude product is subsequently distilled.

The invention relates to a process for preparing vinyl chlorosilanes, that includes thermally and non-catalytically reacting chlorosilane with vinyl chloride at a temperature of 550 to 700&deg; C. by flowing the chlorosilane and vinyl chloride through a ring-gap space in a ring-gap reactor to produce a reaction gas; the ring-gap space having a cross-sectional area and a volume; and, after the flowing, further reacting, adiabatically, the reaction gas in a second zone to produce a hot reaction gas that contains vinylchiorosilane; wherein the second zone has a cross-sectional area that is greater than the cross-sectional area of the ring-gap space; and wherein the second zone has a volume that is in a ratio to the volume of the ring-gap space of 0.15:1 to 1.5:1. The invention also provides an apparatus for carrying out the above process.

Process for the continuous preparation of 3-halopropylorganosilanes

The invention relates to a process for preparing vinylchlorosilanes by thermal non-catalyzed reaction of chlorosilanes with vinyl chloride at from 550 to 700&deg; 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.
