摘　　要：研究了以异丁醛和2,2,4-三甲基-1,3-戊二醇(TMPD)为原料,HY沸石分子筛为催化剂合成了青叶口恶烷的反应,考察了醛醇比、反应时间、带水剂、催化剂用量与其循环使用性对该反应的影响。结果表明:与传统催化体系相比,该体系不仅具有相当的转化率和选择性,而且具有催化剂分离简单、可循环使用的优点。The synthesis of green oxane from isobutyl aldehyde and 2, 2, 4-trimethy-1, 3- pentanediol （TMPD） catalysed by HY zeolite was studied. The effects of ratio of reactants, temperature, solvent, dosage and the recycling of catalyst were investigated. The results showed that not only the conversion of TMPD and the selectivity to green oxane were almost the same, but also the catalyst was easily separated and recycled as compared with conventional catalysts.
