Design of fixed bed reactor for O-xylene oxygenated to phthalic anhydride;

The side chains of o xylene were chlorinated in presence of the catalyst N,N dimethylformamide .

The catalysts of synthesizing phthalic anhydride from naphthaleng,n pentane or o xylene are introduced.

A process approaching 3 and 4 chlorophthalic anhydride in high purity via chloriation of o xylene, oxidation of monochloro o xylene by air in gas phase,and separation of 3 and 4 chlorophthalic anhydride afterwards by distillation is described.

Aimed at ortho-xylene product's poor quality and low yield after capacity expansion of aromatics plant, this paper analyzes the factors affecting ortho-xylene's quality and yield, and offers contermeasures to improve them.

A review on Production technologies,capacity,output and market of ortho-xylene both in and outside China and some suggestions on the development of ortho-xylene in our country.

5-Bromophthalide,a key intermediate of citalopram,was synthesized by treatment of 4-bromo-o-xylene catalyzed by Co(OAc)2-Mn(OAc)2-NaBr with oxygen using acetic acid as solvent in satisfactory yield.
