A process for producing a propargyl alcohol and an allyl alcohol

摘要

The invention relates to a method for producing a propargyl alcohol of formula (I) wherein R1 represents a C1-30 alkyl radical, a C3-8 cycloalkyl radical, a C2-20 alkoxyalkyl radical, a C6-14 aryl radical, a C7-20 alkoxyaryl radical, a C7-20 aralkyl radical, a C7-20 alkylaryl radical or H. According to said method, a corresponding aldehyde of formula R1-CHO is reacted with acetylene in the presence of ammonia and a catalytic quantity of between 0.6 and 10 mol % of an alkaline metal hydroxide, an alkaline earth metal hydroxide or an alkaline metal alcoholate, in relation to the aldehyde used. The invention also relates to a method for producing an allyl alcohol of formulae (II) and (III), from the propargyl alcohol (I) produced according to the invention.
