Acid7
Phthalic Anhydride is a white solid flakes or molten liquid with the molecular formula C 8 H 4 O 3 .It's the principal form of phthalic acid and important industrial chemical of plasticizers for plastics. (arpadis.com)

The pyrazolo pyran derivative 11 resulted from the [3 + 3] cycloaddition of 1 and cinnamic acid, while the Pyrone derivative was prepared by acylation of 12 with two equivalents of acetic anhydride. (bvsalud.org)
The cyclic keto acid 23 was synthesized by the action of succinic anhydride on 12 in the acetic medium, while the latter reacted with cinnamic acid, leading to pyrazole derivative 24. (bvsalud.org)

A qualitative examination of bulk residue taken from the compressed air system revealed the presence of phthalic-anhydride (85449), a potent irritant and a possible decomposition product of the synthetic compressor oil. (cdc.gov)
Oxidation4
The Phthalic Anhydride Unit consists of three basic areas: oxidation, purification, and utilities. (phxequip.com)
The oxidation area, where the crude Phthalic Anhydride is produced, includes the following equipment: compressors, reactors, switch condensers, circulating oil system and tail gas incinerators. (phxequip.com)
The expected development should be transferable to other selective oxidation reactions such as the production of phthalic anhydride and acrylonitrile. (europa.eu)
Amoco began development in 1957 with oxidation processes to produce dimethyl terephthalate and phthalic anhydride. (ineos.com)
