| Hazard Information | Back Directory | [Description]
2-Amino-4-sulfobenzoic acid is freely soluble in hot water, less soluble in cold water. The compound is obtained at a moderate yield by treating 4-methyl-3-nitrobenzenesulfonic acid with sodium hydroxide solution. This acid is used mainly in the manufacture of diazoamino compounds of the R-N=N-NH-R' type. As mixtures with naphthols these compounds have acquired importance as printing inks (Rapidogen dyes). | [Synthesis]
The synthesis method of 2-amino-4-sulfobenzoic acid is as follows: dissolve o-nitrotoluene in pure sulfuric acid at 25-85°C, then add 65% fuming sulfuric acid dropwise to carry out the sulfonation reaction, to obtain 2-nitro-4-sulfotoluene; then carry out |
