    摘要： Improved production of monovinylacetylene by introducing acetylene, at temperatures between 40* and 100*C and under acetylene gas pressures between 0.01 and 10 atmospheres (gauge), into an aqueous, hydrochloric acid solution of copper (I) chloride (Nieuwland catalyst type solution). More particularly, there is added to the catalyst solution an organic monovinylacetylene-solvent boiling at temperatures higher than substantially 150*C, being immiscible therewith and containing at least 40 weight percent of indan together with further mononuclear aromates; the said catalyst solution and the said solvent are mechanically dispersed by introducing acetylene thereinto so as to obtain a homogeneous catalyst liquid having between 25 and 85 percent by volume of the solvent therein; monovinylacetylene is continually stripped off from the dispersed solvent, which is saturated with monovinylacetylene, by introducing an excess of acetylene gas thereinto; and pure monovinylacetylene is recovered from the issuing gas mixture.
