  The present invention relates to a process for the production of vinyl chloride by thermal cracking of 1,2-dichloroethane (EDC) to form a reaction mixture containing vinyl chloride (VCM), hydrogen chloride (HCI), unconverted 1,2-dichloroethane, the impurity 1,3­butadiene and other by-products in which the troublesome by-product 1,3-butadiene is removed. The reaction mixture is quenched and said vinyl chloride is separated from said mixture. Said 1,3-butadiene is removed from said quenched mixture prior to said vinyl chloride separation by reacting with chlorine added to said mixture after addition of a butadiene reduction agent to said mixture. The butadiene reduction agent is selected from the classes of compounds known to or expected to act as radical scavengers. The butadiene reduction agent is an aromatic compound selected from the groups consisting of aromatics with one or more oxygen attached to the ring. Preferably, said butadiene reduction agent is a para-substituted phenol as 4-methoxyphenol, 4-cresol or hydroquinone.

  A haloorganoalkoxysilane is prepared by reacting an olefinic halide with an alkoxysilane in which the alkoxy group(s) contain at least two carbon atoms in a reaction medium to which has been added a catalytically effective amount of ruthenium-containing catalyst and a reaction-promoting effective amount of an electron-donating aromatic compound promoter. The process can be used to prepare, inter alia, chloropropyltriethoxysilane, which is a key intermediate in the manufacture of silane coupling agents.
