Disperse Red 1 Usage And Synthesis

Chemical Properties

Dark red powder

Uses

Disperse orange 3 is used as a dye in nylon and polyester; stocking dye.

Uses

Disperse Red 1 is an azo disperse dye which is water insoluble. Disperse Red 1 can be used to dye polyester and acetate fibers. Dyes and metabolites, Environmental Testing.

Preparation

4-Nitrobenzenamine diazo, and N-ethyl-N-hydroxyethylaniline?coupling

Definition

ChEBI: An azo dye with a structure consisting of nitrobenzene substituted on the 4-position of the phenyl group with a 4-[N-ethyl-N-(2-hydroxyethyl)]phenylazo group.

General Description

Disperse Red 1 (DR1) is a non-linear optical (NLO) material which is a chromophore used as an azobenzene dye. It can form a dipole network that can enhance the electro-optic effect of the non-linear components and can also improve the photorefractive effect.

Properties and Applications

Red: dark red powder, melting point 160 ℃ : insoluble in water, but soluble in ethanol, acetone and benzene. The strong sulfuric acid for yellow brown, diluted to deep crimson red; In nitric acid solution for red; In strong hydrochloric acid also to red solution; In the thick of sodium hydroxide solution for the red light brown. Used for polyester and their blended fabric dyeing and printing, also applies to acrylic, polyamide, vinegar fiber, three vinegar fiber dyeing. Used in high temperature and high pressure method and polyester dyeing of carrier. Dyeing rate medium, not sensitive to temperature, have good levelness and lifting force. Can also be used for the wool, plastic, fur color.
