Preparation method of rubber anti-reversion agent 1,3-bis(citraconimidomethyl)benzene

The invention relates to the technical field of preparation of rubber auxiliaries, in particular to a preparation method of a rubber anti-reversion agent 1,3-bis(citraconimidomethyl)benzene. The preparation method comprises the following steps: (1) mixing citraconic anhydride with a benzene-series solvent in a four-necked flask with a condensing water separator, adding an organic acid catalyst, and raising the temperature for reflux; (2) adding m-xylylenediamine dropwise to the system of the step (1) with an addition time of 0.3-1.0 h, keeping reflux for 1-5 h, and separating water which is brought out by the benzene-series solvent continuously; (3) distilling the benzene-series solvent out, reducing the temperature to 60 DEG C, adding an alcohol solvent, and performing even stirring; and(4) performing cooling, performing filtration, drying the filter cake, collecting the filtrate, and performing recycling. The preparation method has a high conversion rate of the reactants, few by-products and high selectivity of the reaction; and the solvents are all recoverable, less wastewater is generated, and pollution to the environment is small.
