Abstract
Chloromethylation of anthraquinonebenzeneacridone and anthraquinonenaph thaleneacridone with sym-dichlorodimethylether in the presence of concentrated sulfuric acid gave mono- and bis-chloromethyl compounds from the former and mono-, his- and trichloromethyl compounds from the latter almost in pure form. The chloromethyl group was first entered into 12-position of anthraquinone benzeneacridone, to give mono chloromethyl compound then it entered into 10-position to give a bis (chloromethyl) compound. These chloromethylated compounds were derived into pyridinium and isothiuronium salts and their dyeing qualit properties were examined.
