Abstract

In the manufacture of vinyl halides by passing acetylene and hydrogen halide over mercury or a mercury halide, the catalyst is disposed on a continuous body of a non-volatile support so that any catalyst vaporised in the reaction zone is condensed in another part of the support. For example, the reaction tube may contain four grams of mercury or 15.4 grams of gas black, sandwiched between two 40 gram layers of gas black. The direction of flow of the reactants may be periodically reversed.ALSO:In the manufacture of vinyl halides by passing acetylene and hydrogen halide over mercury or a mercury halide, the catalyst is disposed on a continuous body of a non-volatile support so that any catalyst vaporised in the reaction zone will be condensed in another part of the support.
