Solvent Red 41 Usage And Synthesis

Definition

ChEBI: An imine that is 4-methylidenecyclohexa-2,5-dien-1-imine in which the hydrogens of the methylidene group are replaced by 4-aminophenyl and 3-methyl-4-aminophenyl groups. The monohydrochloride salt is the histological dye 'rosanilin'.

Preparation

(a) aniline, p-Methylaniline and O-Methylaniline Triethylamine hydrochloride and its mixture and 1-Nitrobenzene or 1-Nitrobenzene and 1-Methyl-2-nitrobenzene mixture, iron and Zinc chloride in the presence of heating (Zinc chloride method); (b) aniline,?p-Methylaniline?and?O-Methylaniline?mixture and Arsenic acid?heating (Arsenic acidmethod).

Properties and Applications

brilliant blue light red (6-Amino-4-hydroxynaphthalene-2-sulfonic acid ). Soluble in water for red light purple, soluble in ethanol to red. In concentrated sulfuric acid for yellow brown solution, dilute almost colorless. Dye aqueous solution to join sodium hydroxide colorless, have red precipitation.
