Process for preparing condensates of arylsulphonic acids and formaldehyde, and their use |
| abstract |
Process for the preparation of condensates from arylsulfonic acids and formaldehyde by sulfonating aryl compounds which can be obtained by thermal cleavage of a naphthenic residual oil and fractional distillation of the cleavage products of the fraction obtained at 100 to 120 ° C under atmospheric pressure, sulfonation of this aromatic fraction with oleum at temperatures from 120 to 160 ° C in an amount of 0.7 to 1.2 parts by weight of oleum, based on oleum with an SO₃ content of 24% by weight, per part by weight of the aromatic fraction and subsequent condensation of the arylsulfonic acids with formaldehyde in a known manner and use of the condensation products as Dispersants, in particular as dispersants for the preparation of dye preparations. |
