摘要
以大孔强酸性阳离子交换树脂作为催化剂进行了乙酸与一元醇的酯化反应 ,结果表明 ( 1 )乙酸与直链烷基伯醇的酯化率随醇分子链长增大而提高 ,选择性达 1 0 0 %。 ( 2 )异构醇的酯化反应能力顺序为伯醇 仲醇>叔醇 ,叔醇易产生醇分子内或分子间的脱水反应。 ( 3)
The esterification reactions of acetic acid with alcohols using macroporous strong acidic cationic exchange resin as catalyst were proceeded. The results showed that: (1) the esterification converision increase with chain lengh of R group for the esterification reaction of straight chain alkyl alcohol with acetic acid and the selectivity is 100%. (2) the order of reactivity of isomeric alcohol is primarysecondary>terliary and the dehydration reaction take place in malecule or between molecule of tertiary alcohol easily. (3) the reactivity of alcohol decreased by donator substituent in αC or βC of alcohol molecule.
