摘要
以乙酸和异戊醇为原料,采用硫酸铁作催化剂来合成乙酸异戊酯.考察了乙酸与异戊醇的物质的量比、催化剂用量及反应时间对乙酸酯化率的影响.结果表明:硫酸铁对合成乙酸异戊酯具有良好的催化活性,酯化反应的最佳条件为:酸醇物质的量比为1:1.3(乙酸用量为0.1mol),催化剂用量为0.9 g,回流反应1 h,酯化率可达96.69%.
Acetate is synthesized with isoamyl alcohol to produce isoamyl acetate with ferric sulfate as catalyst.The affects of molar ratio of acetic acid to iso-amyl alcohol,catalyst amount and reaction time of the reaction are investigated.The experiment results show ferric sulfate is a good catalyst for synthesizing isoamyl acetate.The optimal conditions are found as follows:molar ratio of acetic acid to iso-amyl alcohol is 1:1.3(amount of acetic acid is 0.1mol),the weight of catalyst is 0.9g,the deaquation reagent is cyclohexane and reaction time is 1h,the yield of the ethyl oleate can be up to 96.69%.
