The invention discloses a preparation method of 4-nitryl-1, 8-naphthalene bimethanoic acid. The preparation method of the invention selects ammonium ceric nitrate to react with acenaphthylene so as to obtain the 4-nitryl-1, 8-naphthalene bimethanoic acid, wherein, acetic acid is a solvent, polyethylene glycol-400 is a phase-transfer catalyst, the ammonium ceric nitrate is a nitrating agent and an oxidant, and the mole ratio of the acenaphthylene: the ammonium ceric nitrate: the polyethylene glycol-400 is 1: 1.0 to 3.0: 0.14 to 2.8. The preparation method of the invention, by selecting the ammonium ceric nitrate to react with the acenaphthylene to obtain the target product at one step, simplifies operation, shortens reaction time, eliminates pollution, saves energy and protects environment.
