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.
