Synthesis of quaternary ammonium salts,butylammonium bromide (TBAB), introduced by Brandstrom, triethyl- benzylammonium chloride (TEBA), initiated by Maskoza, and Stark’s tricaprylmethylammonium chloride (Aliquat 336 or Adogen 464) are more frequently applied. The procedure for the synthesis of these compounds and other simple quaternary

Phase transfer catalyzed reactions under basic conditions,in general, this term is incorrect because, in the majority of cases, bases in these reactions are consumed irreversibly. Since bases can also react as nucleophilic agents, it is necessary to define the reactions proceeding under the action of bases as those in which the crucial step is abstraction

Analytical applications of phase transfer catalysis,cal chemist today. These developments frequently require improvements of the physical and/or chemical properties of the analytes in terms of stability, gas chromatographic (GC) or liquid chromatographic (LC) separation, capillary electrophoretic separation and detection. An important tool to obtain
