Abstract
A process is provided for the preparation of naphthalene-1,3-5,-trisulphonic acid from 1,5-disulphonated naphthalene, which comprises sulphonating 1,5-disulphonated naphthalene, in the form of a mixture which has been obtained by mixing naphthalene and SO3 in the presence of an inert solvent at temperatures in the range of -40 DEG to +20 DEG C., the ratio of SO3 added to naphthalene added having been in the range of 2.5 to 10 mols of SO3 per mol of naphthalene during the entire addition, at 60 DEG to 110 DEG C. in anhydrous sulphuric acid with oleum, with prior or concurrent separation of the inert solvent. The resulting product is a known intermediate for the formation of azo dyestuffs.
