| Abstract: | Methyl formate (MF) is coupled with trioxane to synthesize methyl glycolate(MG) over a sulphuric acid catalyst.The effects are studied of the ratio of HCHO/MF (mol/mol), amount of sulphuric acid, reaction temperature and time on the product yield. The reaction conditions optimized are t =100℃, (HCHO) 3=12g, MF=45 ml, H 2SO 4=10ml, and time=4h, under which the yields of methyl glycolate and methyl methoxyacetate obtained are 36.2% and 24.1% , respectively. |
