Synthesis method
ByN,N-Dimethylaniline undergoes nitrosation and is reduced to form p-aminodimethylaniline, which is then oxidized, vulcanized and condensed with sodium dichromate and sodium thiosulfate, and then Zinc chloride is salted, salted out, filtered and dried to obtain the finished product.
