C.I.Fluorescent Brightener 204,CAS 76482-77-4,784.74,C33H26N12Na2O6S2,Fluorescent Brightener BC,Fluorescent Brightener RA,Blankophor RA

Molecular Formula:C₃₃H₂₆N₁₂Na₂O₆S₂

Molecular Weight: 784.74

CAS Registry Number:76482-77-4

Manufacturing Methods :1,2-Bis(4-amino-2-sulfophenyl)ethene and 2,4,6-Trichloro-1,3,5-triazine (2 Moore) condensation, again with aniline (2 Moore) condensation, then use Ammonium hydroxide ammonification.

Properties and Applications:blue light purple. In peroxide high temperature bleaching solution in use, electrolyte and temperature on direct sex influence is very small; For polyester/cotton blended fabric available pad dyeing; Nylon/cotton blended fabric need in Blankit (C.I.R educing Agent 1:3) under the existence of use. Direct sex is high, not suitable for discharge, but difficult to resist, to chloride and sodium hypochlorite bleaching solution is not stable.
