Abstract: The present invention provides an improved process for manufacturing and recovering butynediol from a reaction mixture comprising an aqueous solution containing formaldehyde, acetylene and suspended catalyst solids in a particular reaction zone, such as a reactor vessel devoid of internal filter assemblies, whereby a product slurry stream comprising butynediol and suspended catalyst solids is removed from the reaction zone and fed to a filter zone external from the reaction zone, the product slurry stream being moved to the external filter zone by injection of a composition comprising acetylene at a point between the reaction zone and the filter zone.
