| Abstract: | Catalytic performances of various acid catalysts for coupling of methyl formate with formaldehyde to form methyl glycolate (MG)and methoxy methyl acetate (MMAc)have been investigated in a portable autoclave.It is found that strong acids have better activities for formation of MG and MMAc;solids acids ,such as SA Rl, SA R2,SA R3,SA M1,SA H1 and SA H2,are also active for formation MG and MMAc, especially SA RI showing a higher activity. The effects of reaction conditions (reaction temperature ,reaction time, ratio of formaldehyde/methy formate, catalyst concentration,etc)are also studied. |
