Description

Application

Isophthalic acid can be used as a reactant to prepare:

Poly(m-phenyleneisophthalamide) by polycondensation with m-phenylenediamine via thermal solid-phase polymerization reaction.

It can also be used as a ligand to synthesize:

Metal coordination polymers by hydrothermal and sonochemical process.
Isophthalic acid-zirconium(IV) nanocomposite, which is used as a precursor to prepare crystalline tetragonal ZrO₂via thermal decomposition method.
