    Synthetic Tannins

  • The didepside of phenolsulphonic acid is obtained by condensing carbomethoxyphenolsulphonic chloride with sodium phenolsulphonate in the presence of the calculated amount of caustic soda.

    Synthetic Tannins

  • On condensing sodium phenolsulphonate with nitrotoluenesulphonic chloride, reducing the condensation product and condensing the latter with _p_-toluenesulphonic chloride, a compound similar to the above is obtained --

    Synthetic Tannins

  • SO_2Cl by treatment with PCl_5, and the chloride thus obtained further condensed with sodium phenolsulphonate, saponified, and the solution acidified, the pure tridepside

    Synthetic Tannins

  • Each 10 gm. of this moist paste were treated in the cold with (_a_) free phenolsulphonic acid; (_b_) sodium phenolsulphonate; (_c_) crude Neradol and (_d_)

    Synthetic Tannins

  • Attempts were made at condensing partly neutralised phenolsulphonic acid; the latter was obtained by mixing equal quantities of phenolsulphonic acid and sodium phenolsulphonate (prepared by exactly neutralising phenolsulphonic acid with a concentrated solution of caustic soda).
