Usage

Uses

Mordant Yellow 10 is a monoazo dye used in wool textiles. Mordant Yellow 10 is used as organic reagent for spectrometric determination of iron(III) as well as in the study of other metal complexations.

Preparation

4-Aminobenzenesulfonic acid diazotization, and 2-Hydroxybenzoic acid coupling.

Properties and Applications

deep green light yellow. Deep yellow powder. Soluble in water for yellow, hardly soluble in Cellosolve, Etanol and Chloroform, insoluble in other organic solvent. In concentrated sulfuric acid to red light yellow, yellow after diluted for accompanied by precipitation; In concentrated nitric acid for yellow solution. Its aqueous solution to join concentrated hydrochloric acid and Sodium hydroxide are yellow. Dyeing encounter copper ion colour and lustre is a little dark. Mainly used for wool fabric dyeing, also can be used for silk, nylon post-mordant dyeing, leather and fur dyeing. Can with other media dye spell to use, can be used for wool and a variety of fiber with bath dyeing, can be in Chromic acetate pretreatment of wool or on silk dyeing.
