Basic Dye C.I. 46025 ((byFormaldehyde and4-Methylbenzene-1,3-diaminereaction, product and amino reaction hydrochloric acid and ammonium chloride heating or remove ammonia, melting with ferric chloride and oxidation) and Dimethyl sulfateor and Methyl 4-methylbenzenesulfonatereaction. Note: the market many similar alkylation Dye, they are through the Basic Dye C.I. 46025 or 46065 (from Benzaldehyde and 4-Methylbenzene-1,3-diaminediazo, cyclization and condensation with ferric chloride oxidation and) alkylation. When use and inorganic acid or alkyl halide reaction, amino is alkylation, but use of Dimethyl sulfateorMethyl 4-methylbenzenesulfonateor Ethyl p-toluenesulfonate, then the formed real around totally heterocyclic compounds.
