| Abstract: | Dimethylfumarate was synthesized by one step reactien of Maleic anhydride with methanol in the presence of modified HZSM 5. The yield of dimethylfumarate can be obtained over 90%. The influence of reaction conditions such as the mole ratio of anhydride to methanol, the quantity of the catalyst, reaction temperature and reaction time was determined. The catalyst was repeatedly used at least 10 times and, the catalytic activity was not decreased basically. |
