    Abstract: A 2-aryl-4,6-diamino-1,3,5-triazine in conc. H2SO4 is treated with nitrosylsulphuric acid at 80-160 degrees C and the reaction mixture poured into water. In an example 2-phenyl-4,6-diamino-1,3,5-triazine in conc. H2SO4 was treated with nitrosylsulphuric acid in conc. H2SO4 at 140 degrees C, cooled to 70 degrees C and poured into ice-water to obtain an 88% yield of 2-phenyl-4,6-dihydroxy-1,3,5-triazine.

    Abstract: gp.-contg. anthraquinone dyes. anthraquinone dyes:- (where X is amino or C1-3 alkyl; Y is H or halogen, amino, alkylamino or alkylmercapto with 1-3C, phenyl-amino or phenyl-mercapto in which the Ph can contain halogen and/or methyl, ethyl or methoxy, and R is C1-10 aliphatic hydrocarbon, opt. substd. by Cl, Br, CN, C1-5 alkoxy, carboxylic acid ester, dialkylamino, carboxylic acid amide or phenyl) are new dispersion dyes for dyeing and printing synthetic textile materials, e.g. fibre material of polyester and polyamide. The dyeings and prints have good light fastness, abrasion fastness and high heat fastness.
