Description
Phthalic Anhydride is a versatile intermediate in organic chemistry, since it is bi- functional and cheaply available. It undergoes hydrolysis and alcoholysis. Hydrolysis by hot water forms ortho-phthalic acid. This process is reversible: Phthalic anhydride re-forms upon heating the acid above 180oC.[2] Hydrolysis of anhydrides is not typically a reversible process. However, phthalic acid is easily dehydrated to form phthalic anhydride due to the creation of a thermodynamically favorable 5-membered ring.

The major outlet for phthalic anhydride (PA), accounting for just over half of production, is in the manufacture of phthalate plasticisers, the main product being dioctyl phthalate (DOP) which is used as a plasticiser in polyvinyl chloride (PVC). Hence, the consumption of PA is mainly dependent on the growth of PVC, which is sensitive to general economic conditions as it is consumed mainly in the construction and automobile industries. Health and environmental issues that surround phthalates used in plasticisers for PVC could also hinder future growth prospects.

Uses :
In the manufacture of alkyd resins for paints and varnishes
Phthalic anhydride esters like dop, diop, dnp, didp etc. Are the most acceptable plasticizers for pvc products. Whereas they are the characterized by their low volatility, high water resistance and better electrical properties, other phthalate plasticizers like bbp, bop, dchp satisfy fast gelling and low temperature requirement of vinyl resin based products.
In the manufacture of unsaturated polyester resins
Finds applications as dye intermediate and in the manufacturing of pigments. Whereas anthraquinone and its derivatives are used in dyes, pigments like phthalocyanines are used as coloring agents in laminates varnish, printing ink, and plastic industries.
In the manufacture of tetrachloro phthalic anhydride which finds application in reactive fire retardant in unsaturated polyesters.
