Industrial chemicals cas 85-44-9 99.5% phthalic anhydride priceProduct Description
Phthalic anhydride is the organic compound with the formulaC6H4(CO)2O.It is the anhydride of phthalic acid.Phthalic anhydride is a principal commercial form of phthalic acid. It was the first anhydride of a dicarboxylic acidto be used commercially. This colourless solid is an important industrial chemical, especially for the large-scale production of plasticizers for plastics.

The primary use of phthlic anhydride is as a chemical intermediate in the production of plastics from vinyl chloride.Phthalate esters,which function as plasticizers, are derived fromphthalicanhydride. Phthalate plasticizers are used for the production of flexible PVC products such as cables, pipes and hoses, leather cloth,shoes,film for packaging etc.
Phthalic anhydride has another major use in the production of polyester resinsand other minor uses in the production of alkyd resins used in paints and lacquer;certain dyes; insect repellents; and polyester polyolfor polyurethanes.It is also utilized as a rubber scorch inhibitorand retarder.
Phthalic anhydride is a versatile intermediate in organic chemistry, in part because it is bi-functionaland cheaply available. Hydrolysisby hot water forms ortho-phthalic acid. Hydrolysis of anhydridesis not typically a reversible process. Phthalic acid is however easily dehydrated to form phthalic anhydride. Above 180℃,phthalic anhydride re-forms.The most probable human exposure to phthalic anhydride is through skin contact or inhalationduring manufacture or use. Studies show that exposure to phthalic anhydride can cause rhinitis,chronic bronchitis, and asthma.Company Information
