Name:C.I.Sulphur Yellow 2,C.I.53120

Molecular Structure:

C.I.Sulphur Yellow 2,C.I.53120,CAS 1326-66-5,Sodyesul Liquid Yellow GLCF,Sulphur Light Yellow GC,Sulphur Yellow GR,Sulphur Yellow GC,Sulphur Yellow GCD,Sulphur Yellow 2G

CAS Registry Number:1326-66-5

Manufacturing Methods : 100 of the N,N’-diformyl-1,3-diamino-6-methylbenzene, 6 7 sets 4-(4-Aminophenyl)benzenamine and 400 a mixture of sulfur in the 140 ~ 150 ℃ calcination, and in 15 hours will the temperature rise to about 218 ~ 220 ℃ (BIOS 1155, 35-36). And with high temperature or large proportion of the sulfur get color is red dye, and less sulfur cross 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. Brown powder. Insoluble in water: in sodium sulfide solution for yellow brown solution; In concentrated sulfuric acid partly dissolved, dilution after yellow sulfur precipitation. Dyeing content in alkaline insurance powder in a slight change: in sodium hypochlorite in almost all fade; Join concentrated sulfuric acid into dark orange.
