詳細

詳細

Phthalic acid (PA, PTA), also called as 1,2-benzenedicarboxylic acid is an aromatic carboxylic acid. 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. Its mineralization by photocatalysis using TiO₂/UV system has been studied. It also is used as a potential tyrosinase inhibitor.

アプリケーション

Phthalic acid may be used as a catalyst for the thiocyanation of aromatics and heteroaromatics and as an interfacial protector for the preparation of ordered mesoporous γ-alumina. It may be used as a model compound in understanding the adsorption of aromatic carboxylic acids on gold surfaces.
