Abstract:The 3-chlorobutanol was prepared from 1,3-butanediol by acetylation and ester interchang. The effect of the reaction conditions were investigated. The temperature of the acetylation is lower than 50?℃; the mole ratio of 1,3-butanediol and acetyl chloride is 1∶1.2; the time of ester interchange is 10?h; the total yield of is 75%.
Key words:chlorobutanol; 1; 3-butanediol synthesis
