Abstract

2 - (o - Methoxyphenyl) - 4,6 - dichlortriazine is obtained from the 4,6-dihydroxy body by reaction with phosphorus oxychloride and pentachloride. 2 - (o - Methoxyphenyl) - 4,6 - dihydroxy - triazine is obtained by treating o-methoxybenzoylbiuret with aqueous caustic potash. o-Methoxybenzoylbiuret is obtained by heating o-methoxybenzoyl dicyandiamide with aqueous hydrochloric acid. o - Methoxybenzoyl dicyandiamide is obtained by treating dicyandiamide in acetone with caustic potash to its potassium salt, and reacting this with o-methoxybenzoyl chloride.ALSO:The invention comprises 2 - (o - methoxyphenyl) - 4,6 - di - (41 - methoxyanthraquinonyl-amino)-triazine, which is a red vat dye and is prepared by heating 2-(o-methoxyphenyl)-4,6-dichlortriazine (see Group IV (b)), with 1-amino-4-methoxyanthraquinone. An example of the condensation is given wherein the reactants are heated in nitrobenzene.
