Basic dye C.I. 46025 (by Formaldehyde?and 4-Methylbenzene-1,3-diamine?reaction, product and amino reaction hydrochloric acid and ammonium chloride heating or remove ammonia, melting with ferric chloride and oxidation) and Dimethyl sulfate?or and Methyl 4-methylbenzenesulfonate?reaction. Note: the market many similar Basic dye, they are through the Basic dye C.I. 46025 or 46065 (from Benzaldehyde and ?4-Methylbenzene-1,3-diamine?diazo, ?cyclization, and then by oxidation with ferric chloride into a base derived. When alcohol and mineral acid or halide burning reaction, amino group is alkylated, but the use of Dimethyl sulfate or Methyl 4-methylbenzenesulfonate?or Ethyl p-toluenesulfonate, the resulting formation of a real acridine heterocyclic compounds.
