Abstract: In the process for the preparation of vinylsilanes by reacting acetylenic hydrocarbons with silanes which have at least one silicon-bonded hydrogen atom in the liquid phase in the presence of a catalyst, the silane is added to the liquid phase. In particular, the reaction is carried out at superatmospheric pressure, and the spent acetylenic hydrocarbon is replenished during the reaction while maintaining a pressure which is constant during the entire reaction.

Abstract: A process for preparing xylylenediamine, comprising the steps of ammoxidizing xylene to phthalonitrile and hydrogenating the phthalonitrile, which comprises contacting the vaporous product of the ammoxidation stage directly with a liquid organic solvent or with molten phthalonitrile (quench), partly or fully removing components having a boiling point lower than phthalonitrile (low boilers) from the resulting quench solution or suspension or phthalonitrile melt and, after the low boiler removal and before the hydrogenation, removing products having a boiling point higher than phthalonitrile (high boilers).
