Description
General description
Phthalic acid (PA, PTA), also called as 1,2-benzenedicarboxylic
acid[2] is
an aromatic carboxylic acid.[1] It
is the ortho form of the three phthalic acid isomers, the
other two being isophthalic acid (meta form) and terephthalic acid (para form).
PA is the starting material in the synthesis of plasticizers. A study on
toxicity reveals that PA shows in vitro and in vivo toxicity.[2] Its
mineralization by photocatalysis using TiO2/UV system has been
studied.[3] It
also is used as a potential tyrosinase inhibitor.[4]
Application
Phthalic acid may be used as a catalyst for the thiocyanation of
aromatics and heteroaromatics[6] and
as an interfacial protector for the preparation of ordered mesoporous γ-alumina.[5] It
may be used as a model compound in understanding the adsorption of aromatic
carboxylic acids on gold surfaces.[1]
