Synthetic method of aromatic aziridine cross-linking agent

The invention discloses a synthetic method of an aromatic aziridine cross-linking agent (figure 1). The method comprises three chemical synthesis steps: (I) reacting 1-amino-2-propanol with chlorosulfonic acid to obtain amino-isopropyl sulfate; (II) carrying out an intra-molecular nucleophilic substitution reaction on amino-isopropyl sulfate in alkali liquor, removing sulfate radical groups, and carrying out ring closing to generate an intermediate 2-methyl aziridine; and (III) directly reacting the obtained 2-methyl aziridine with isophthaloyl dichloride in a mixed system of alkali liquor andan organic solvent without separation, and carrying out separation and purification to obtain a final product 1,1'-(1,3-phthaloyl)bis(2-methyl-aziridine). The commodity name is HX-752, and the aromatic aziridine cross-linking agent has wide application. A liquid-liquid homogeneous or heterogeneous reaction is adopted, the reaction conditions are mild, the process is simple and easy to control, and the yield is high. Besides, the synthesis method has the advantages of fewer byproducts and low waste discharge amount, is suitable for large-scale production, and has favorable industrialization prospects.
