CAS Registry Number:12262-38-3

Manufacturing Methods :  100 of the N,N’-diformyl-1,3-diamino-6-methylbenzene, 67 copies of 4-(4-Aminophenyl)benzenamine and 400 copies of sulfur cross mixture in 140 ~ 150 ℃ calcination, and in 15 hours will the temperature rise to about 218 ~ 220 ℃ (BIOS 1155, 35-36). With high temperature or large proportion of the sulfur cross get color is red dye, and less sulfur proper high temperature generation quantitative hydrogen sulfide, results of green light yellow dye.

Properties and Applications:  deep green light yellow to dark red light yellow. In the sodium sulfide solution good solubility, In concentrated sulfuric acid partly dissolved, dilution after yellow sulfur precipitation.
