Embodiment 1~5
[0016] According to the method of the present invention, use acidic resin catalyst, cooperate suitable process condition, carry out catalytic esterification synthetic dimethyl maleate with maleic anhydride and methanol as raw material, concrete condition and reaction result are shown in Table 1.
[0017] Table 1 Catalytic Esterification of Maleic Anhydride and Methanol to Synthesis of Dimethyl Maleate
[0018]
[0019] It can be seen from Table 1 that in the maleic anhydride catalytic esterification reaction section, the conversion rate of maleic anhydride is 100%, and the selectivity of dimethyl maleate is greater than 99%.
Embodiment 6~12
[0021] According to the inventive method, use hydrogenation catalyst (catalyst composition is by weight), coordinate suitable process condition, take dimethyl maleate as raw material catalytic hydrogenation synthesis dimethyl succinate, concrete condition and reaction result are shown in table 2.
[0022] Table 2 Synthesis of Dimethyl Succinate by Catalytic Hydrogenation of Dimethyl Maleate
[0023]
[0024] As can be seen from Table 2, in the catalytic hydrogenation reaction section of dimethyl maleate, the conversion rate of dimethyl maleate and the selectivity of product dimethyl succinate are greater than 99.8%.
