Abstract
Chloromethylation of arylaminoanthraquinones such as four kinds of α-mono-substituents composed of anilino, ο- and m-toluidino and mesidinoanthraquinones, three kinds of bis-compound composed of 1, 4-, 1, 5-, and 1, 8--bis(p-toluidino)-anthraquinones, and 1-hydroxy-4-p-toluidinoanthraquinone were carried out by use of sym-dichlorodimethylether in concentrated sulfuric acid. Each of the chloromethylated compound was isolated and their properties were clarified. The chloromethylated compounds were derived into pyridinium and isothiuronium salts and their availability as the dye has been investigated.
