    摘要： An organic ester e.g. 1,4-diacetoxybutane is hydrolyzed with an alkali metal or an alkaline earth metal hydroxide to a corresponding alcohol, the reaction being rapidly effected by having present a hydroxyl-containing compound. In a preferred embodiment, the hydroxyl-containing compound to be present is the very compound to be produced e.g. 1,4-butanediol is to be produced from 1,4-diacetoxybutane and there is present during the reaction of hydrolysis an earlier produced 1,4-butanediol.
