    摘要: There is disclosed a method for producing acetylene alcohol compounds in a continuous process, which are produced via ethynylation in which ketones containing a group --CH.sub.2 COCH.sub.2 --, are condensed with acetylenes at a temperature of about 20 to 50.degree. C. under a pressure of about 10 to 30 kg/cm.sup.2 in the presence of a quaternary ammonium hydroxide anion exchange resin having strong basicity in an aprotic solvent by feeding a reactant mixture at an LHSV range of 0.1 to 5.0 and the reactant mixture comprises the acetylene, the ketone and the solvent at a molar ratio of 1.0:0.2-3.0:1.0-4.0.
