| 摘 要： | 本文研究了几种新催化剂对ＤＨＰ（邻苯二甲酸二庚酯）合成的催化性能，实验表明自行合成了固体超强酸催化性能良好，本文讨论了以固体到超酸为催化剂时，反应条件如反应和 酐与庚醇配比，催化剂用量，反应时间等对全成反应的影响，结果得出最佳反应条件；催化剂量０．６ｇ反应物配比（酸酐：庚醇）为１００ｇ：２００ｇ；反应时间为３小时ＤＨＰ产率可达９５．５％。

| Abstract: | In this paper,several methods of catalystic synthesis of DHP was studied. The solid Superacidwas Synthesized and used to Catalyze the DHP Synthesis. The influent Conditions ofreactants on the yield of estes,suchas the weight ratio of phthalic anhydirde to heptadiene,the amount of catalyst used,the reaction time,are investigated,the result shows that the appropriateconditions should be: Weight of catalyst:0.6g rammer,weight ratio of hpthalic anhydrideto heptadiene: 100g/200g;reaction time: 3 hours;The yield of DHP is about 95. 5 %. |
