A method for preparing an antioxidant

The invention provides a preparation method for an antioxidant. The method includes: subjecting a compound shown as formula (III) and a compound shown s formula (IV) to dehydration reaction in the presence of an organic solvent. The method is characterized in that in the dehydration reaction process, the reaction generated water and part of the organic solvent are separated from the reaction system, and water division treatment is carried out, then the water-containing organic solvent subjected to water division treatment contacts a first dehydrating agent, and the organic solvent obtained after contact is returned to the reaction system. Specifically, n is 1 or 2, x is 1 or 2, y is an integer of 0-6, R1 and R2 are not a straight chain or branched chain alkyl group with a hydrogen atom or carbon atom number of 1-6 at the same time, and R3 and R4 are not a straight chain or branched chain alkyl group with a hydrogen atom or carbon atom number of 1-6 at the same time. By adopting the method provided by the invention to prepare the antioxidant, the dehydration effect of the reaction system can be enhanced, and accordingly the reaction efficiency and product yield can be enhanced. (formula III and formula IV).
