| 摘 要： | 采用"一锅煮"的方法,在无有机溶剂存在下,将自制的催化剂400PW/SBA(40)(简记为PW/SBA)用于过氧化氢氧化环己烯制备己二酸的绿色工艺中。通过己二酸合成预实验,确定了n(过氧化氢)/n(环己烯)=5.47;用正交实验法和单因素实验法优化反应工艺条件,考察了反应时间、催化剂用量、反应温度和加料方式对己二酸收率的影响。确定出较优工艺条件为:反应时间9 h,温度80℃,催化剂用量1.75 g,n(H2O2)/n(环己烯)=5.47(环己烯以5.3 mL,0.049 7 mol计),反应开始时加入半量过氧化氢,反应3.5 h后再加入另外半量过氧化氢〔w(H2O2)=30%〕。通过3次平行实验,己二酸产品的收率可达73.5%,质量分数可达99.7%。并对PW/SBA进行了表征,得出其氮气吸附等温线和BJH孔容曲线。

| Abstract: | Adipic acid is synthesized by means of a one-pot reactive mode with cyclohexene and hydrogen peroxide(w(H2O2)=30%) using the modified catalyst 400PW/SBA(40)(brief note PW/SBA).The process is the scientific method of clean synthesis without organic solvent.Three steps were taken in this study to optimize the conditions of the synthesis process of adipic acid.First of all,the basic route of synthesizing adipic acid was determined by a pre-experiment program.Then,the orthogonal experiment method and the single... |
