Studies on Phase-Transfer Catalysis Properties of Triethyl Benzyl Ammonium Chloride

In This paper,the phase transfer catalyst three ethyl benzyl chloride(TEBA) was prepared from triethylamin and benzyl chloride After quaternized reactive,the yield was higher than 80%.Through experiments to explore,the optimum reaction conditions were determined:isopropanol as the solvent,n(N(C2H5)3):n(C6H6CH2Cl)=1: 1,T=82℃～84℃,t=8h;Its structure was confirm by IR.The three ethyl benzyl ammonium chloride used in the synthesis reaction of Benzoic acid(aromatic hydrocarbon oxidation) and p-nitroanisole(nucleophilic substitution),the product yield significantly improved,reaction time was significantly shorter,and further identified as a phase transfer catalyst TEBA in the above two reactions in the best application conditions.
