Phthalic anhydride is a cyclic anhydride, is an important chemical raw material, especially for plasticizer manufacturing.
Dibutyl phthalate, Dioctyl phthalate are important plasticizers.
Phthalic anhydride and polyols (such as glycerol, pentaerythritol) can generate polyarylate resin in a condensation way, used in the paint industry;
if an unsaturated acid with ethylene glycol happening condensation, the resulting chemical is unsaturated polyester resin, for the manufacturing of insulating paint and glass fiber reinforced plastics.
Phthalic anhydride is a raw material of benzoic acid, terephthalic acid, also used in pharmaceutical synthesis.
- Mainly used in the production of plastic plasticizer, alkyd resin, dye, unsaturated resin, and some medicine and pesticide.
- Applications in industry and organic synthesis.
- 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.
- Widely used in industry for the production of certain dyes. A well-known application of this reactivity is the preparation of the anthraquinone dye quinizarin by reaction with para-chlorophenol followed by hydrolysis of the chloride.
