Method for co-producing dimethyl hexynediol and methyl butynol

The invention relates to a method for co-producing dimethyl hexynediol and methyl butynol, which comprises the following steps: by taking acetone and acetylene as raw materials, potassium hydroxide as a catalyst and an organic solvent as a dispersing agent, reacting acetone with normal-pressure or low-pressure acetylene at a lower temperature to generate a methyl butynol-potassium hydroxide complex; and mixing the complex with acetone, and quickly reacting through a high-temperature reaction tube to generate dimethyl hexynediol. And the reaction product is respectively recovered by adopting a mode of firstly separating methyl butynol through distillation and then separating dimethyl hexynediol through water extraction. The method has the characteristics of low reaction temperature, short reaction time, less side reaction, less catalyst dosage and the like. 一种联产二甲基己炔二醇和甲基丁炔醇的方法，以丙酮和乙炔作原料，氢氧化钾作催化剂，有机溶剂作分散剂，先将丙酮与常压或低压的乙炔在较低温度下反应生成甲基丁炔醇-氢氧化钾络合物，再将其与丙酮混合后快速通过高温反应管反应生成二甲基己炔二醇。反应产物则采取先蒸馏分离甲基丁炔醇，后水萃取分离二甲基己炔二醇的方式分别回收产
