| 摘 要： | 在固定床反应系统中，考察了几种固体酸催化剂对于乙酸／丙烯酯化反应的催化作用，研究了温度、压力、进料空速以及原料中水的含量对催化剂活性的影响。实验发现：对于ＨＤ－１催化剂，在１３０℃、１１ＭＰａ、乙酸进料空速（ＬＨＳＶ）为２５２ｈ－１的条件下，乙酸单程转化率可达８８６％，生成乙酸异丙酯的选择性可达９９％，催化剂连续运转１００ｈ，活性无明显的变化。

| Abstract: | Esterification of acetic acid with propene which is carried out in fixed bed system and catalyzed by solid acid catalysts is introduced.The catalysis of several types of solid acid catalysts on this reaction is investigated.The exchange resin catalyst and supported phosphorus acid and supported phosphotungstic acid possess good activity and selectivity.In the case of using HD-1 catalyst that is made from exchange resin,the conversion of acetic acid can get up 88.6% with 99.7% selectivity for isopropyl acetate at 130℃ and 1.1 MPa and about 2.52h -1 space velocity.After streamed for 100 hours,no obvious decrease in activity of catalyst HD-1 is observed. |
