C.I.Leuco Sulphur Blue 7,C.I.53440,CAS 69900-21-6,1327-57-7,Leuco Sulphur Blue L-BR

CAS Registry Number:69900-21-6,1327-57-7

Manufacturing Methods : 4-(4-Amino-3-methylphenylamino)phenol with Sodium polysulfide solution in return 106 ~ 112 ℃ heating 50 hours, then 70 ~ 80 ℃ blow air make precipitation. This indophenol is by o- Toluidine and 4-Nitrosophenol in sulfuric acid in the condensation, then use Sodium sulfide reduction and have to. Sodium sulfide increase in the proportion of sulfur content and high temperature vulcanization, color is red and more bright-coloured dye.

Properties and Applications: red light blue to blue light purple. Dark brown liquid. PH value is 13.3; Viscosity 5.9 x 10-3 pa s.; Settleability (3000 r.p.m.); No separation, no settlement. In the Sodium sulfide solution solubility is good, for green grey; In concentrated sulfuric acid for blue purple, dilution of dark after precipitation.
