Abstract
|
|
|
|
The hydrolysis of fungicidal N-[1-(benzotriazol-1-yl)benzyl]aniline (BBA) molecule in the presence of cationic cetyltrimethylammonium bromide (CTABr) and anionic sodium laurylsulfate (NaLs) micellar solutions has been studied kinetically. The Micellar catalysis effect shows that the rate is slightly accelerated by the addition of the anionic NaLs at high pH and the binding constant (Ks) is 1.45×10⁴ M^(-1). This result presumably is due to the electrostatic stabilization by the anionic micelle of the developing carbocation in the transition state rather than the hydrophobic character (π: 4.93) of (BBA).
