摘要:
在前人研究的基础上 ,提出以乙醇、甲醛为原料 ,采用固体酸 (苯磺酸 )作催化剂 ,研究各种因素对合成二乙氧基甲烷反应过程的影响 ,在催化剂用量、原料配比、反应时间、搅拌速度一定的条件下 ,首先考察反应温度对合成过程的影响 ,选择适宜的反应温度 ;其次考察其它因素对反应过程的影响 ,通过研究确定二乙氧基甲烷合成过程的工艺参数 ;在其它条件不变的情况下 ,与浓盐酸催化法进行比较 ;通过系统的研究为进一步研究和工业化试验提供条件 .
Abstract:
A new method for diethoxymethane synthesis using ethanol and formaldehyde as raw material and a solid acid ( benzene sulfonic acid) as catalyst was studied. Different effects on the synthesis process were discussed in detail. The influence of temperature on the process of the synthesis was considered primarily at fixed catalyst amount, raw material ratio, reaction time and stirring time to optimize the temperature for the reaction. The effects of other factors on the synthesis process were then also considered to optimize the process parameters. The method was also compared with that using chlorhydric acid as catalyst. The results were of some value for further research and industrialization.
