| 摘 要： | 间歇式应釜中，采用骨架Ni催化剂，对衣康酸加氢制备甲基丁二酸的工艺条件进行了研究，探讨了溶剂、反应时间、反应温度、催化剂用量及循环次数对加氢反应的影响。结果表明，最佳反应条件为：甲醇为溶剂，反应时间为60min，反应温度为50℃，催化剂质量分数为10％，此时，衣康酸转化率为99．14％。催化剂循环使用5次后，衣康酸转化率仍在95％以上。采用傅里叶红外光谱、核磁共振对产物的结构进行了分析。

| Abstract: | Synthesis of methylsuccinic acid was investigated in a batch reaction kettle by hydrogenation of itaconic acid using skeletal Ni as catalyst. The effects of reaction con- ditions such as solvent kinds, reaction time, temperature, dosage and recycling times of catalyst were examined. The obtained optimum conditions were reaction time 60 min, temperature 50 ℃, catalyst dosage 10%, and using methanol as solvent. Under above conditions, the conversion of itaconic acid was 99.14%. The conversion of itaconic acid was still over 95% after the catalyst was reused 5 times. The structure of product was characterized by FT-IR and 1H NMR. |
