Method for preparing dimethyl acetamidophthalate
-
Paragraph 0027-0028, (2020/08/22)
The invention relates to a method for preparing dimethyl acetamidophthalate. The method comprises the following steps: dissolving nitrophthalic anhydride in methanol, adding a graphite-phase carbon nitride supported cuprous catalyst (g-C3N4/Cu2O) and acetic anhydride, and carrying out reacting to obtain dimethyl acetamidophthalate. 200-300 mg of the graphite-phase carbon nitride supported cuprouscatalyst (g-C3N4/Cu2O) is used for every millimole of nitrophthalic anhydride, and 2.0-3.0 mmol of acetic anhydride is used for every millimole of nitrophthalic anhydride.
