摘要:The present invention provided a continuous flow process for the synthesis of phenylhydrazine salts and substituted phenylhydrazine salts. Diazotization, reduction, acidic hydrolysis and salifying with acids are innovatively integrated together. Using acidic liquids of aniline or substituted aniline, diazotization reagents, reductants and acids as raw materials, phenylhydrazine derivative salts is obtained through the synthesis process, which is a three-step continuous tandem reaction including diazotization, reduction, acidic hydrolysis and salifying. The described synthesis process is a kind of integrated solutions, which is carried out in an integrated reactor. The feed inlets of the integrated reactor are continuously filled with raw materials. In the integrated reactor, diazotization, reduction, acidic hydrolysis and salifying are carried out continuously and orderly, and phenylhydrazine salts or substituted phenylhydrazine salts is obtained in the outlet of the integrated reactor without interruption. The total reaction time is no more than 20 min.

标 题:Synthesis of nanofibers of polyaniline and substituted derivatives
发明人：EPSTEIN ARTHUR J; CHIOU NAN-RONG
权利人:OHIO STATE UNIVERISTY
摘要:Novel, simple methods are presented directed to the synthesis of nanofibers of polyaniline and substituted derivatives. The production of these fibers is achieved via various methods by controlling the concentration of aniline monomer or substituted aniline derivatives or an oxidant in the reaction medium and maintaining said concentration at a level much lower than conventional polyaniline synthesis methods. Methods are disclosed relating to the use of a permeable membrane to control the release of a monomer and/or oxidant as well as a bulk polymerization method.
