Uses and applications

What the substance is used for, by industry and function

In manufacture of dyes.

How it is made

By heating reduction product of anthraquinone with sulfuric acid & glycerol.

(A) from anthranol & glycerol by condensation by means of sulfuric acid (anthranol is made from anthraquinone), (b) from anthracene in sulfuric acid solution by addition of glycerol & heating to 100-110 °c until anthracene disappears. Reaction mass is then diluted with water, salted out & purified.
