摘　　要：研究了HAlMCM-41分子筛催化邻苯二酚与环己酮、丁酮、丙酮、丙醛、丁醛、异丁醛、戊醛、正己醛、正辛醛、苯甲醛、二苯甲酮等十余种醛(酮)的缩合反应.考察了反应时间、酚与醛(酮)的配比、HA1MCM-41分子筛用量、硅铝比、催化剂重用次数等因素对邻苯二酚与醛(酮)反应的影响.结果表明,当邻苯二酚与醛(酮)物质的量比为1:1.4,催化剂用量为3.5g/mol邻苯二酚,反应4h,分子筛n(SiO_2)/n(Al_2O_3)为15时,选择性一般在99.4%以上,转化率也一般在85.6%以上,因此,HAlMCM-41分子筛对邻苯二酚与醛(酮)的反应有较好的催化性能.The acetalization and ketalization of various aldehydes and ketones with catechol using HA1MCM-41 zeolite as catalyst were studied. Results showed that HA1MCM-41 was an efficient catalyst for the acetalization and ketalization with high conversion and selectivity in mild conditions. The best reaction condition is that molar ratio of catechol to aldehydes or ketones was 1 ： 1.4, catalyst amount was 3.5 g/mol catechol, reaction time was 4 h, n（SiO2）ln（A1203）= 15. Under this condition, conversion was over 85.6% and selectivity was over 99.4%.
