Oxidation of o-Xylene to Phthalic AnhydrideNew plants for the manufacture of are usually based on an o- feedstock: There are several factors in favor of its use: the number of carbon atoms rcmains the same in the product and feedstock - unlike naphthalene, there is no oxidative degradation...
Xylene is metabolized through the P-450 mixed-functionmicrosomal enzymesystem in the endoplasmic reticulum of the liver. The biotransformation of xylene through side-chain oxidation and aromatic oxidation results in metabolites of methylbenzyl alcohols, methylbenzaldehyde, and methylbenzoic acids (toluic aci...
Kinetics of vapor phase oxidation of o-xylene has been studied over sintered and compacted vanadium pentoxide in a continuous stirred tank catalytic reactor in the temperature range of 450–517°C at atmospheric pressure. The major product obtained is phthalic anhydride. The other products are ...
Xylenes can undergooxidation where the side methyl groups are oxidized to give a carboxyl group (COOH)yielding a carboxylic acid. The particular acid produced depends on the isomer oxidized. Wheno-xylene is oxidized phthalic acid is produced, and when p-xylene is oxidized terephthalic acidresults....

The liquid phase oxidation of p-xylene is very promising. As described above, the AMOCO process is a homogeneous catalytic system that, despite having excellent yields, utilizes acetic acid as a solvent and bromide compounds, such as hydrobromic acid (HBr) or sodium bromide (NaBr); this creates...
The general purification methods listed under xylene are applicable. The o-and p-isomers can be removed by their selective oxidation when a m-xylene sample containing them is boiled with dilute HNO3 (one part conc acid to three parts water). After washing with water and alkali, the product ...
