摘　　要：丙烯酸丁酯是由丙烯酸和正丁醇在一定温度、催化剂的作用下合成的。本文通过分析催化剂损耗的途径,对反应系统温度、重组分分解器反应温度等进行了调整,以降低催化剂(对甲苯磺酸)的使用量,减轻对甲苯磺酸对阀门、垫片等设备的腐蚀。结果表明,提高反应系统温度对降低催化剂的影响最大,每提高1℃,可以减少催化剂使用量5%以上;重组分分解器温度每提高1℃,可减少催化剂使用量1.38%。Butyl acrylate is synthetized by acrylic acid and butanol at certain temperature and catalyst.In this article,the loss route of catalyst was analyzed,and the temperature of reaction system and heavy constituent decomposition system was adjusted to decrease the amount of catalyst,which can alleviate the corrosion to valve and shim by catalyst.The result indicates that the amount of catalyst could be reduced 5%by increasing 1℃of the temperature of reaction system,and the amount of catalyst could be reduced 1.38%by increasing 1℃of the temperature of heavy constituent decomposition system.
