This book involves a detailed study on nucleophilic sulfonation of decyl halides and benzyl halides in o/w microemulsions and emulsions formed with the two-tailed cationic surfactants dioctyldimethylammonium chloride/bromide, R2(Me)2N+Cl-/Br-. At the concentrations employed, phase separation occurred and emulsions formed in most of the samples. The chloride counterion reacted with the halide precursors to form an intermediate, decyl chloride, and a side product, benzyl chloride. The tendency of sodium decyl sulfonate to remain at the interface resulted in lower conversion with increasing...
