摘 要:分別以濃硫酸、氯化鐵、硫酸銅為催化劑催化合成醋酸環(huán)己酯,考察了有無(wú)結晶水的硫酸銅對酯化反應的影響。在較優(yōu)催化劑CuSO4.5H2O催化下,考察了反應時(shí)間、催化劑用量、醇酸比等因素對酯化率的影響。研究表明,當醇酸摩爾比為1.6∶1,硫酸銅用量對反應物摩爾比為1∶50時(shí),環(huán)己烷作帶水劑,反應2h,酯化率可達96.7%,且催化劑可重復使用。

LIANG Xue-Bo; XIAO Yang; GUO Can-Cheng(College of Chemistry and Chemical Engineering; Hunan University; Changsha 410082; China)
Abstract:Cyclohexyl acetate was synthesized by oil of vitriol,ferric chloride and copper sulfate,respectively,and the influence of copper sulfate containing water and no-water for the reaction was discussed.The influence of reaction time,dosage of catalyst and molar ratio of cyclohexanol/acid were investigated in the presence of copper sulfate used as catalyst.The results showed that the esterification yield could reach 96.7% when the mole ratio of alcohol/acid was 1.6 ∶ 1,the mole amount of copper sulfate was 1 ∶ 5...
Key words:cyclohexyl acetate; copper sulfate; catalysis; synthesis
