2,6-Naphthalenedicarboxylic acid is an organic compound with the formula C10H6(CO2H)2. This colorless solid is one of several isomers of naphthalenedicarboxylic acid. It is a precursor to the high performance polyester polyethylene naphthalate (PEN, poly(ethylene-2,6-naphthalene dicarboxylate)).[1] It is also used in the synthesis of some metal-organic frameworks.

Preparation

It was first prepared by Robert Evert and Victor Merz [de] in 1876 by hydrolysis of 2,6-dicyanonaphthalene.[2][3]

1,8-Naphthalenedicarboxylic acid can be isomerized to 2,6-naphthalenedicarboxylic acid via the intermediacy of the dipotassium dicarboxylates.[2] It is also produced by oxidation of 2,6-diisopropylnaphthalene.[4]
