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.

发明人：BAER TED A
权利人:ZOECON CORP
摘要:An improved process for preparing substituted amino acids and lower alkyl esters thereof, and intermediates therefor, comprising reacting a substituted aniline, HCN and an aldehyde to form a nitrile, converting the nitrile to an imidate salt with a strong acid and an alcohol, hydrolyzing in situ the imidate salt to the ester with addition of water, and optionally converting the ester to the salt or free acid. The acids are useful intermediates in the synthesis of pesticides.

发明人：RODRIGUEZ GEORGE
权利人:EXXONMOBIL CHEM PATENTS INC
摘要:Zwitterionic compositions of matter comprising cations [Ct] + and anions connected together with substantially rigid fluorinated linking groups are described. These zwitterionic compositions serve as cocatalysts. They activate olefin polymerization catalysts, and can dissolve in aliphatic solvents. Synthesis and polymerization are illustrated.
