Изобретение относится к усовершенствованному способу получения 3-метил-1-бутин-3-ола, который находит широкое применение в органическом синтезе. Цель изобретения заключается в повышении выхода 3-метил-1-бутин-3-ола, конверсии ацетона и безопасности процесса. Ацетилен подвергают взаимодействию с ацетоном при атмосферном давлении в присутствии каталитических количеств полугидрата гидроксида калия KOH•0,5 H2O в ДМСО, содержащем 3 - 5% воды в качестве промотора реакции, при температуре 10 - 30oC. Выход 3-метил-1-бутин-3-ола 98%, конверсия ацетона 96%.The invention relates to an improved method for producing 3-methyl-1-butyn-3-ol, which is widely used in organic synthesis. The purpose of the invention is to increase the yield of 3-methyl-1-butyn-3-ol, acetone conversion and process safety. Acetylene is reacted with acetone at atmospheric pressure in the presence of catalytic amounts of potassium hydroxide hemihydrate KOH • 0.5 H 2 O in DMSO containing 3 - 5% water as a reaction promoter, at a temperature of 10 - 30 o C. Yield 3-methyl- 1-butyn-3-ol 98%, acetone conversion 96%.
