OXIDATION BEHAVIOR OF L-THREONINE BY N-BROMOPHTHALIMIDE IN MICELLAR SYSTEM OF CTAB

The effect of cationic surfactant Cetyltrimethylammonium bromide (CTAB) molecules on the oxidation of L-threonine by N- bromophthalimide (NBP) has been studied at 308 K. The reaction exhibits first order dependence on NBP and fractional positive order on L-threonine and negative fractional order dep...
