| Solvent Red 41 Usage And Synthesis |
| 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). |
| 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’. |
