Abstract:
A process for the production of 2,6-naphthalene dicarboxylic acid, consisting essentially of, contacting, at a temperature of about 120.degree. C. to about 300.degree. C., a poly(alkylene 2,6-naphthalate), water, and an organic carboxylic acid, other than 2,6-naphthalene dicarboxylic acid, containing 2 to about 20 carbon atoms, andprovided that said carboxylic acid is about 0.1 to about 50 volume percent of said water, or said organic carboxylic acid is about 0.05 to about 25 weight percent of said poly(alkylene 2,6-naphthalate), or said carboxylic acid is about 0.1 to about 50 volume percent of said water, and said organic carboxylic acid is about 0.05 to about 25 weight percent of said poly(alkylene 2,6-naphthalate).
