3-Hydroxy-4'-methoxy-2-naphthanilide Chemical Properties,Uses,Production

Uses

3-Hydroxy-4'-methoxy-2-naphthanilide is mainly used as a base agent for dyeing and printing cotton fabrics red. It has moderate affinity and coupling ability for cotton and its performance is similar to that of Naphthol AS-OL (CI37530). It is also used for dyeing vinylon, viscose fiber, silk, diacetate fiber and cotton printing, and can also be used as an intermediate for fast pigments.

Preparation

p-Anisidineand 3-Hydroxy-2-naphthoic acid condensation.

Properties and Applications

Light brown powder evenly. In the ethanol frond-like crystal shrinkage, melting point for 229 ~ 230 ℃. Insoluble in water solution and sodium carbonate, soluble in pyridine. In the sulfuric acid is shallow brown in the solution; Sodium hydroxide solution for yellow in the liquid. Sensitive to air. Mainly used for cotton fabrics, PVA, viscose, silk and vinegar fiber dyeing and printing of cotton fabric. Can be used for the manufacture of pigment fast. This product to cotton affinity medium, coupled ability medium.
