摘要
合成了5种漆酚金属聚合物,对它们依次进行红外光谱分析,并用这一系列聚合物作为催化剂合成醋酸异戊酯,筛选出了最佳漆酚金属聚合物催化剂UR—Fe—C。考察了原料配比、反应时间等因素对酯化反应的影响。确定了以UR—Fe—C为催化剂合成醋酸异戊酯(IA)的最佳反应条件:醇酸摩尔比为0.6:1,催化剂用量为醇质量的2.3%~3.4%,反应时间3h,酯化得率达88%,产品纯度达99.5%。且该催化剂具有腐蚀性小,可以重复使用等优点。
A series of urushiol-metal polymers were synthesized and their properties were characterized by IR method, in which urushiol-Fe-C polymer was used as catalyst to synthesize isoamyl acetate. Factors affecting esterification yield such as material ratio, time of reaction and catalyst have been studied. The optimum conditions are as follows: material ratio of isoamyl alcohol to glacial acetic 0. 6 : 1 ; dosage of catalyst 2.3 % - 3.4 % of isoamyl alcohol; reaction time 3 h ; yield of isoamyl acetate ( IA ) 88 %. The purity of product is 99.5 %. This catalyst has the advantage of less corrosion and can be reused.
