ABSTRACT:
Monovinylacetylene is produced by an improved process, wherein acetylene is introduced at temperatures within the range 40.degree. and 100.degree. C and under acetylene gas pressures within the range 0.01 and 10 atmospheres (gauge) into a Nieuwland catalyst type solution being an aqueous copper(I) chloride solution in hydrochloric acid, which is used in admixture with between 0.1 and 10 weight% of an alkali metal salt of an aminocarboxylic acid or of an aminosulfonic acid, and wherein acetylene is introduced into the catalyst solution jointly and simultaneously with an inert organic solvent extractant and stripping agent for the resulting monovinylacetylene, the solvent being in vapor form and being continuously passed through the catalyst solution so as to continually strip off monovinylacetylene originating from dimerized acetylene.
