What is Phthalic Aid?

Phthalic acid is an ambrosial dicarboxylic acid, with blueprint C6H4(COOH)2. Phthalic acid is used mainly in the anatomy of the anhydride to aftermath added chemicals such as dyes, perfumes, saccharin, phthalates and abounding added advantageous products. Phthalic acid, if begin in tissues or biofluids arises from acknowledgment to these phthalate products. Phthalate is an ecology actinic of acute accessible affair because letters of its abeyant accident to macho changeable health, getting decidedly associated with bargain agent absorption to pesticide absorption in men's urine. Within the changeable tract, the macho is alluringly accessible to the furnishings of anti-androgens during development due the assurance on the admixture and activity of androgens for the masculinization of the macho changeable tract. The adeptness of phthalates to abolish androgen admixture during development and to abet testicular dysgenesis calm with cryptorchidism and hypospadias has aloft ample concern.

It is a dibasic acid, with pKa's of 2.89 and 5.51. The monopotassium salt, potassium hydrogen phthalate is a accepted acid in analytic chemistry. Typically phthalate esters are able from the broadly accessible phthalic anhydride. Abridgement of phthalic acid with sodium admixture in the attendance of baptize gives the 1,3-cyclohexadiene derivative.

Phthalic acid is used as an alive additive in polyesters and alkyd resins. It is aswell used as plasticizers for polyvinyl chloride and added polymers. It is aswell advantageous in the assembly of anthraquinone, phenolphthalein and phthalocyanine pigments. It serves as an amoebic reagent in the assembly of phthalates. It is used to adapt 1,3-cyclohexadiene by abridgement application sodium amalgam.
