Process for the production of 1-aminobenzene - 5-ss-sulphatoethylsulphone -2-sulphonic acid and 1 -aminobenzene - 5-vinylsulphone - 2-sulphonic acid and the alkali metal and alkaline earth metal salts thereof |
| abstract |
1-Amino-2-sulphophenyl 5- beta -sulphatoethyl sulphone and 5-vinyl sulphone and optionally their alkali metal and alkaline earth metal salts are prepared from 1-aminophenyl 3- beta -sulphatoethyl -3- beta -hydroxyethyl or 3-vinyl sulphone using a mixture of sulphuric acid/sulphur trioxide or sulphuric acid/chlorosulphonic acid under the conditions specified in Claim 1. The compounds obtained can be used as diazo components for synthesising azo dyes by diazotisation and coupling. |
