Abstract

Quinine forms a salt with 2 : 3-dihydroxy-naphthalene-O-mono-acetic acid which is practically tasteless. The salt is formed by interaction of the base with the acid in a solvent, or by double decomposition of a water-soluble salt of quinine and of the acid in aqueous solution. An example is given. 2 : 3 - Dihydroxynaphthalene - O - monoacetic acid is prepared by treating 2 : 3-dihydroxynaphthalene with chloracetic acid in equimolecular proportions.
