1,3-Benzenediamine, 4-methyl-, reaction products with 4-nitrobenzenamine, p-phenylenediamine and sulfur Usage And Synthesis

Preparation

75 parts of??4-Methylbenzene-1,3-diamine ,?62.5 parts of? 4-Nitrobenzenamine, 16.2 parts of??Benzene-1,4-diamine and 287 parts of mixture of sulfur in the 220 ~ 240 ℃ calcination 10 hours, and its products in the Sodium sulfide solution in 90 ~ 95 ℃ processing, sifting. Garnish with sulfuric acid precipitation. Use different number of the following example intermediates, in a similar way, get more partial brown color of dye: 93.5 parts of?4-Methylbenzene-1,3-diamine , ?47 parts of 4-Nitrobenzenamine, 40 parts of ?Benzene-1,4-diamine, 380 parts of?sulphur.

Properties and Applications

brown light olive. In the Sodium sulfide solution solubility good, for yellow brown; In concentrated sulfuric acid for yellow brown, dilution after yellow brown precipitation.
