摘要
在 DKZ 固体酸上对己酸和乙醇的酯化反应进行了研究。讨论了反应温度、醇/酸摩尔比、液体进料空速(LHSV)以及原料中含水量对 DKZ 固体酸催化活性的影响。试验证明,在固定床反应器内,用95%的乙醇和化学纯己酸为原料,在反应温度115℃下,醇/酸摩尔比为5:1,LHSV 为6小时^(-1)的条件下,己酸的转化率可达98%以上。500小时的寿命试验还表明,DKZ 固体酸的催化性能是稳定的。
In this paper,the esterification reaction of caproic acid with ethanol overDKZ solid acids was studied.The effects of reaction temperature,molar ratio ofethanol/caproic acid,LHSV and watar content of raw material on catalyticactivity of DKZ solid acid were discussed.it was found that for the fixed-bedreactor,at a reaction temperature of 115℃,a molar ratio of ethanol/caproic acid5:1 and a LHSV of 6h^(-1),the conversion of caproic acid can reach over 98%.Thelife experiment of 500-hours also confirmed that the catalytic property of DKZsolid acid was stable.
