摘要
采用浸渍法制备了负载型ZrOCl2.8H2O/USY催化剂,并用XRD、SEM等对其进行了表征。以ZrOCl2.8H2O/USY为催化剂,考察了其对月桂酸与月桂醇酯化反应的催化性能。以月桂酸的转化率为考察指标,讨论了催化剂活性以及各种因素如催化剂用量、反应溶剂、反应时间对该酯化反应月桂酸的转化率的影响。实验结果表明,n(月桂酸)∶n(月桂醇)=1∶1,30%(质量分数)ZrOCl2.8H2O/USY为催化剂,反应溶剂为氯代苯,当催化剂用量为反应物总质量的5.0%,溶剂回流条件下反应16 h,月桂酸的转化率达95.2%。
The catalyst of ZrOCl2·8H2O supported on molecular sieves USY was prepared using impregnation method,which was then characterized by means of XRD and SEM.The catalytic properties were examined by the catalytic esterification of lauric acid and lauryl alcohol.Based on the investigation index of the conversion rate of lauric acid,the effects of catalyst activity and other conditions such as reaction solvent,catalyst loadings,and reaction time on the conversion rate of lauric acid were investigated.The results show that the conversion rate of lauric acid was up to 95.2% in the esterification of lauric acid and lauryl alcohol under the following optimum conditions：the mole ratio being 1∶1,5.0 % quantity of catalyst,reflux temperature of solvent and reaction time of 16 h,30%（mass fraction） ZrOCl2·8H2O/USY as catalyst,and chlorobenzene as solvent.
