Abstract
The title reaction has been studied spectrophotometrically as a function of [], [isoleucine], [H2SO4], and temperature in absence and presence of cationic micelles of cetyltrimethylammonium bromide (CTAB). Under pseudo-first order conditions, the reaction follows first order kinetics with respect [isoleucine]. At lower values of [CTAB] (≤40.0 × 10−4 mol dm−3), the catalytic effect of cationic micelles of CTAB may be due to the incorporation/solubilization of isoleucine and
into the interfacial region of Stern- and palisade layer.In contrast, at higher values of [CTAB] (≥40.0 × 10−4 mol dm−3), the inhibitory effect was observed due to the dilution.Thermodynamic parameters were computed by studying the reactions at different temperatures (303–333 K). Plausible mechanisms are suggested.
