Phthalic acid

Phthalic acid (IUPAC systematic name: benzene-1 2-dicarboxylic acid) is an terephthalic acid Uses Phthalic acid is used mainly in the form of the saccharin phthalates and many others History Phthalic acid was obtained by French catalyst The catalytic oxidation of phthalic anhydride and a subsequent hydrolysis of the anhydride is one of the new production methods

Ethanoic anhydride can't be said to dissolve in water because it reacts with it to give ethanoic acid There is no such thing as an aqueous solution of ethanoic anhydride Boiling point Ethanoic anhydride boils at 140C This is because it is a fairly big polar molecule and so has both van der Waals dispersion forces and dipole-dipole attractions It doesn't however form hydrogen bonds

Phthalic anhydride is used to make polymeric resins called alkyd resins which are used as coatings especially for appliances and automobiles The para isomer terephthalic acid is also used to make polymers—namely polyesters (see below Derivatives of carboxylic acids: Carboxylic esters) Several important acids contain an aromatic ring but because the carboxyl group is not bonded

Parallels exist with the production of phthalic anhydride: While older methods use naphthalene modern methods use o-xylene as feedstock Reactions The chemistry of maleic anhydride is very rich reflecting its ready availability and bifunctional reactivity It hydrolyzes producing maleic acid cis-HOOC–CH=CH–COOH With alcohols the half-ester is generated e g cis-HOOC–CH=CH
