摘要
本文主要研究了甲醇与钾汞齐在铁/碳催化剂作用下合成甲醇钾的工艺。实验结果表明各主要因素对收率的影响是不同的。其中温度影响最大,催化剂用量次之,反应时间对收率影响最小。通过正交实验和单因素实验优化了反应条件,确定了最佳催化剂量为0.5%,反应温度为60℃,反应时间10分钟。实验结果表明甲醇钾浓度对反应速率和产率的影响不大。
A process for preparation of the potassium methylate with the potassium-mercury amalgam and methanol using Fe/C as catalyst was provided. The results demonstrated that the influences of factors on the yield were different. The influences were in the order： temperature 〉 weight ratio of Fe/C catalyst 〉reaction time. The optimum reaction experiments and signal factor experiments as follow： the conditions were determined by orthogonal weight ratio of Fe/C catalyst to potassium-mercury amalgam was 0.5%,the temperature was 60℃,the reaction time was 10 minutes. The result also demonstrated that the influences of potassium methylate＇s content on the reaction rate and yield was little.
