Abstract

Condensation of naphthalenesulphonic acids with aldehydes or with substances yielding aldehydes in an acid medium, to give products containing two or three napthalenesulphonic acid groups linked by aldehyde residues, is effected above 100 DEG C. at increased hydrostatic pressure. Preferred reactants are the 2-sulphonic acid and formaldehyde (or paraformaldehyde, hexamethylenetetramine or trioxymethylene) but the 1-sulphonic acid, the 1,6- ,2,6- and 2,7-disulphonic acids, acetaldehyde, paraldehyde, propionaldehyde, butyraldehyde, glyoxal and furfural are also mentioned.
