Uses
A polybasic acid intended for use as components of resinous and polymeric coatings that contact food.
Uses
2,6-naphthalenedicarboxylic acid is an important product for the manufacture of high strength and excellent dyeing properties of polyester fibers and F class insulation material, is an important monomer performance PEN, PBN, liquid crystal polymer (LCP) and polyurethane resin pharmaceutical and fine chemicals raw material.
Uses
2,6-Naphthalenedicarboxylic acid (H2ndc) can be used in the formation of metal-organic coordination polymers (MOCPs) for potential applications in various fields such as adsorption, separation, and magnetism. It can also be used as a monomer in the production of polyesters. H2ndc can also be used in the synthesis of a metal-organic framework (MOF), which can further be used as a drug carrier.
Definition
ChEBI: Naphthalene-2,6-dicarboxylic acid is a dicarboxylic acid. It derives from a hydride of a naphthalene.

Synthesis
2,6-Naphthalenedicarboxylic acid (2,6-NDA) is selectively synthesized from 2-naphthoic acid (2-NCA) and carbon tetrachloride in aqueous sodium hydroxide solution under mild conditions using cyclodextrin (β-CyD) as a catalyst[1]. The specific reaction steps are as follows:
Three mmol of 2-naphthalenecarboxylic acid/2-NCA), 0,8 mmol(0,05 g) of copper powder, and 3,0 mmol of β-CyD were added to 30 mL of 30 wt.-% aqueous sodium hydroxide solution. The reaction was started with the addition of 8,5 mmol of carbon tetrachloride and was continued at 60°C for 7 h with magnetic stirring under nitrogen. Then, the residual carbon tetrachloride was removed by evaporation under reduced pressure.
