Product Detail

Properties

Vat Yellow 1

CAS：475-71-8

Molecular formula：C28H12N2O2

Molecular weight：408.41

Properties: Orange (or golden) powder. Soluble in hot nitrobenzene, slightly soluble in o-chlorophenol and pyridine, insoluble in water, acetone, ethanol, toluene or chloroform. It is dark orange in concentrated sulfuric acid and produces yellow precipitation after dilution. Blue in alkaline sodium bicarbonate solution; Green in acid reducing solution. The dye is easy to be reduced to leuco and is not easy to be oxidized.

Application: VAT yellow 1 is mainly used for dyeing and printing of cotton, vitamin and vitamin / cotton, polyester / cotton. It has good affinity for cotton fiber and good levelness. Because it is difficult to oxidize, it is oxidized with hydrogen peroxide or sodium perborate to get a bright color. It is also used in the manufacture of organic pigments.
