  • The aromatic compounds form, as a rule, sulphonic acids with much greater facility.

    Synthetic Tannins

  • Like other "strong" and "weak" acids this sulphonic acid exercises a strongly swelling influence on pelt.

    Synthetic Tannins

  • The sulphonic acid group may also be directly introduced either by concentrated, or by fuming sulphuric acid, or by elimination of halogen by the action of sodium or silver sulphite on the halogen derivatives of the aliphatic compounds.

    Synthetic Tannins

  • Similarly, halogenated compounds and alcohols react with concentrated or fuming sulphuric acid forming sulphonic and hydrosulphonic acids respectively.

    Synthetic Tannins

  • All natural tannins are unaffected by this treatment, ligninsulphonic and other sulphonic acids cause opalescence.
