摘要
采用超重力技术,对生产环氧氯丙烷中的甘油和氯化氢合成二氯丙醇氯化反应进行了研究。结果表明,使用己二酸作为催化剂,在反应温度110℃、压力0.15MPa的条件下,反应停留时间可以由传统的10 h缩短至4 h。超重力反应技术大大强化氯化反应中甘油与氯化氢的传质效率,减少反应停留时间,可大大减少工业化占地面积和设备投资。
The chlorination of dichloropropanol from glycerol and hydrogen chloride in the production of epichlorohydrin was studied by using high gravity technique.The results show that the residence time of the reaction can be shortened from 10 h to 4 h under the condition of 110℃and 0.15 MPa.Supergravity reaction technology greatly enhance the mass transfer efficiency of glycerol and hydrogen chloride in chlorination reaction,reduce the residence time of reaction,and can greatly reduce the industrial footprint and equipment investment.
