| 摘 要： | 以Dawson结构磷钨杂多酸为催化剂,由过氧化氢氧化环己醇合成了己二酸。通过正交实验和单因次实验考察了各因素对反应的影响,确定的优化工艺条件为:n(环己醇):n(过氧化氢):n(磷钨杂多酸)= 100:450:0.15,反应温度为100℃,反应6 h,己二酸分离收率达90.1%。催化剂重复使用5次,收率仍可达到79.8%

| Abstract: | Adipic acid was synthesized by H_6P_2W_(18)O_(62)?nH_2O catalyzed oxidation of cyclohexanol with 30%by weight of hydrogen peroxide in the absence of organic solvent and phase-transfer catalysts. Under the optimal conditions,i.e.,molar ratio of C_6H_(10)O:H_2O_2:H_6P_2W_(15)O_(62)?nH_2O=100: 450:0.15,reaction temperature 100℃and reaciton time 6 h,the isolated yield of adipic acid could reach 90.1%.The catalyst could be reused for 5 times with the yield of the isolated adipic acid still being above 79.8%. |
