摘要:
为了减少生产过程中的废液排放以及降低生产成本，利用稀土固体超强酸催化氯乙酸和十二醇合成氯乙酸十二酯的方法替换原有的氯乙酰氯和十二醇缩合的方法.以稀土(镧)钛系固体超强酸为催化剂，用单因素试验法研究了催化剂用量、醇酸摩尔比、反应时间以及催化剂重复使用次数对酯化反应产率的影响，并对合成的产品进行气相色谱分析后得到了优化工艺参数.以加入0.09 mol十二醇为基准，醇与酸物质的量之比为1∶1.15，催化剂用量的质量分数为2.8%(以醇的质量计)，反应温度为135 ℃，反应时间3.0 h.结果表明，在优化工艺条件下氯乙酸十二酯产率可达97.79%，且该催化剂易于回收，经过简单处理可重复使用多次，催化效果好、操作简单、无环境污染等.
Abstract:
To reduce the effluent discharge and reduce the cost in the process of production, the rare earth solid superacid catalyze chloroacetic acid and lauryl alcohol synthesis method was used to replace the method of Chloroacetyl chloride and lauryl alcohol condensation. The four factors affecting the esterification reaction, such as the amount of catalyst, the molar ratio of acid and alcohol, the reaction time and the used times of catalyst were studied by single factor experiment method ,and the products were analyzed by gas chromatography to get the optimized process parameters. the optimum reaction conditions were obtained when lauryl alcohol of 0.09 mol was added as benchmark, n(alcohol)/n(acid) was 1.15∶1,ω(catalyst) was 2.8 %(based on dodecanol) , reaction temperature was 135 ℃, and the reaction time was 3 h. The results show that the yield can reach 97.79% under the optimized condition; the catalyst is easy to recover through simple processing, and can be reused many times. This method is excellent for the esterification reaction because of simple operation, no environment pollution, etc.
