INDIGOSOL O, DISODIUM SALT Chemical Properties,Uses,Production

Uses

Indigosol O is an indigo dye used for cotton.

Preparation

(a) in the presence of Pyridine , with Chlorosulfonic acid treatment C.I. Vat Blue 1 leuco; (b) in the Pyridine with metal (such as copper, iron, zinc, etc) and Sulfur trioxide source (such as Sulfur trioxide, Chlorosulfonic acid or Methyl chlorosulfonate, etc.) processing C.I. Vat Blue 1. The above two kinds of situation after alkaline, filter out insolubles, remove Pyridine and salting out.

Properties and Applications

Navy blue to red navy. Soluble in water and Etanol. In the Sodium hydroxide solution without change; In concentrated sulfuric acid for brilliant green. Mainly used for dyeing cotton fabric. Alkaline reduction leuco for yellow; Acid reduction leuco colorless. To cotton direct sex low, good levelness. Can also be used to viscose and adhesive/cotton blended fabric dyeing.
