COPE elimination reaction observed in the biodegradation of quaternary ammonium surfactants

Abstract

Fig. 1 Olefin generation (CH 2 NCHC 16 H 33 ) from distearylmethylamine N-oxide in the presence of 5 mm DSDMA X (X = OH, F, Cl, Br) at pH 7.5, 37 °C in 0.01 m K 2 HPO 4 , 5 mm MgCl 2 , containing 10 mg ml 21 protein. Aliquots from the reaction vessel (10 ml) were taken after 15 min, analysed for remaining N-oxide and CH 2 NCHC 16 H 33 by GC-MS techniques.
