Synthesis of dodecylbenzene over supported HF/USY catalyst;

A facile synthesis of dodecylbenzeneamine has been inveetigated which features thenitration of dodecylbenzene and the followed reduction of the adduct.

In accordance with the principle of sulfonation, the dodecylbenzene was used as the material and SO 3 vaporized from 65% fuming sulfuric acid as the sulfonating agent, and the art conditions were studied also.

The high temperature chain oil formulated with alkylated biphenyl ether possesses excellent oxidative steady ability and lubricity,which can satisfy the lubricating requirements of high temperature chain.

A novel technology for preparation of alkyldiphenylamine(ADPA)from α-olefin(C~=_(14))and diphenylamine with phosphotungstic acid supported on silica as catalyst was investigated.

Study on the Synthesis of Diphenylmethane over Immobilized AlCl_3 Catalysts;

Blanc chloromethylation reaction of aryl compounds with chloromethyl methyl ether for preparation of diphenylmethane derivatives was carried out in chloroaluminate ionic liquids prepared from AlCl_3 and 1-alkylpyridinium or 1-methyl-3-alkylimidazolium halide quaternary ammonium salts.

This paper discussed the new way of synthesis of 3-dodecyl anthraquinone sulfonic acid with dodecyl benzene and ophthalmic anhydride through the process of Friedel-Crafts reaction, cycling reaction and sulphonate.
