Summary:The invention discloses a method for catalyzing selective nitration of 1-methoxynaphthalene by using a zeolite molecular sieve. The method comprises the following steps: S1: calcining a zeolite molecular sieve catalyst for 6h at the temperature of 550 DEG C; S2: taking and placing 6mmol of 1-methoxynaphthalene and 5mL of acetic anhydride into a 50mL single-mouthed flask, carrying out oscillating to completely mix the 1-methoxynaphthalene and the acetic anhydride, then, adding 0.1g-1.1g of zeolite molecular sieve catalyst, slowly adding 2mmol of bismuth nitrate with stirring, and carrying out awater-bath stirring reaction for 12h at the constant temperature of 25 DEG C; S3: recovering the catalyst after the reaction ends up, then, adding 20mL of deionized water, heating to 40 DEG C, and continuing to carry out a reaction for 1h so as to thoroughly hydrolyze the acetic anhydride into acetic acid; S4: carrying out extracting, washing and drying; and S5: carrying out separating and purifying.
