摘要
对环戊烯选择性氧化制备戊二醛的工艺进行了研究,进行了高性能负载型催化剂的制备和性能评价,对影响反应过程的主要因素进行了考察,并通过反应进程的分析以及工艺条件的优化,确定了较为适宜的氧化工艺条件。实验表明,采用三段氧化工艺,在W(叔丁醇)∶W(环戊烯)=6、W(过氧化氢)∶W(环戊烯)=3、反应温度为35~37℃、反应时间24h左右的条件下,环戊烯的转化率为100%,戊二醛的收率在85%以上。
The selective oxidation of cyclopentene to glutaraldehyde was studied.The preparation and performance evaluation of high-performance supported catalyst were carried out.The main factors affecting the reaction process were investigated.Through the analysis of reaction process and the optimization of process conditions,the more suitable oxidation process conditions were determined.The experimental results show that the conversion of cyclopentene is 100%and the yield of glutaraldehyde is more than 85%under the conditions of W(tert butyl alcohol):W(cyclopentene)=6,W(hydrogen peroxide):W(cyclopentene)=3,reaction temperature is 35~37℃,reaction time is about 24 hours.
