SULPHO GROUP-CONTAINING AROMATIC COMPOUNDS, THEIR PRODUCTION AND USE AS DISPERSANTS OR LEVELLING AGENTS IN DYEING TEXTILES OR TANNING LEATHER

摘要

Compounds and mixtures of compounds obtainable by condensation of sulphonation products of defined alkyl-substituted naphthalenes and sulphonation products of optionally alkyl-substituted diphenylethers with formaldehye and optionally treated with further components, are valuable interface-active compounds suitable as assistants in various application fields, in particular as dispersing or levelling agents in the dyeing with disperse dyes or as tanning-assistants or dyeing-assistants for leather.
