SUGGESTED MECHANISM FOR THE FORMATION OF 3-HYDROXY-2-METHYLBENZOICACID FROM 3-AMINONAPHTHALENE-1,5-DISULPHONIC ACID.

Abstract

A mechanism has been suggested for the formation of3-hydroxy -2-methylbenzoic acid (1), obtained from 3-aminonaphthalene-1,5-disulphonic acid (3) by alkali fusion in an autoclave. The various steps involved are discusscd and the possible mode of degradation of One of the naphthalene rings to give the final benzenoid product is delineated.
