The synthesis of diethoxy methane was studied using ethanol and formaldehyde as the raw materials and toluene-p-sulfonic acid as the catalyst.It was found that when the mole ratio of ethanol to formaldehyde was 3.97:1,the mole ratio of toluene-p-sulfonic acid to the total raw materials 7%,the reaction temperature 25℃,the stirring speed 70 r/min and the reaction time 10 min,the yield of DEM was about 90.4%.Under the above reaction conditions,the yield was about 62.3% using HCl as the catalyst,and the amount of water in the product was higher and the waste acid in the continuous reaction would pollute the environment.In addition toluene-p-sulfonic acid can be used repeatedly.Therefore,this synthesis method is useful the practical production of diethoxy methane.
