Used extensively in chemical manufacturing, pharmaceuticals, dyes and pigments, plastics/polymers, and adhesives/sealants. It is a derivative of beta-nitrostyrolene, which has wide application in medicine, agriculture, production development, and the like, and primarily can be used as an effective component of an AIDS medicament in the field of medicine.

Preparation

A preparation method of 2, 5-dimethoxy-beta-nitrostyrene, which comprises the following steps: step (1): adding materials 2, 5-dimethoxybenzaldehyde, nitromethane, ammonium acetate and an organic solvent into a reaction kettle, wherein the mass ratio of the materials 2, 5-dimethoxybenzaldehyde to nitromethane to the organic solvent to ammonium acetate is 1:0.7-0.9:4-5:0.25-0.3, and reacting for 4-10 hours at the temperature of 70-80 ℃; step (2) of adding an aqueous solution to the reaction solution obtained in step (1) and washing the mixture to separate the mixture into an aqueous layer and an organic layer; and directly cooling and crystallizing the organic layer, and centrifuging to obtain a finished product of the 2, 5-dimethoxy-beta-nitrostyrene.
