| 摘 要： | 以Dawson结构磷钼酸铵为催化剂,用30%H2O2水溶液为氧化剂,研究了十八醇液相选择氧化制十八酸的反应。考察了催化剂用量、反应时间、H2O2用量、反应温度等因素对催化反应的影响。通过单因素检验和正交试验确定了反应的最佳条件:催化剂用量为十八醇质量的3.7%,n(H2O2)/n(醇)比值为10∶1,反应温度为95℃,反应时间为4h,收率可达95.3%。催化剂重复使用5次后,十八酸的收率仍可达91.6%。 |

| Abstract: | Octadecanoic acid was synthesized by (NH_4)_3P_2Mo_(18)O_(62) catalyzed oxidation of octadecanol with 30% hydrogen peroxide. Effects of catalyst amount, 30% H_2O_2 amount, reaction temperature, reaction time were investigated. The optimal conditions were obtained by orthogonal experiments, under the optimal condition which, i.e. m(catalyst)= 3.7% (relative to the dosage of octadecanol), reactant molar ratio of octadecanol : hydrogen peroxide with 1.0 : 10.0 and reaction temperature of 95℃, reaction time of 4 h, the isolated yield of octadecanoic acid achieved 95.3%. The catalyst could be reused for 5 times and the isolated yield of octadecanoic acid was still above 91.6 %. |
| Keywords: | octadecanol octadecanoic acid (NH_4)_6P_2Mo_(18)O_(62) H_2O_2 clean catalytic oxidation |
