| titleOfInvention | Process for the preparation of water-soluble azo dyestuffs |
| abstract | Abstract of the Disclosure: A new and very advantageous process had been found for the preparation of azo dyestuffs by diazotation and coupling in which the synthesis is carried out without the hitherto usual addition of an acid, with the proviso that at least one of the diazo and coupling components contains at least one acid group. Besides the saving of reaction material and sub-sequently of alkali for neutralization of the reaction medium and isolation of the dyestuff, highly concentrated solutions of the dyestuff and salt-free or practically salt-free dyestuffs ran be obtained, and waste-water is no longer charged with big amounts of salts. |
