摘要:
The alkaline hydrolysis of dimethylformamide has been studied at 40°C In mixed micelles of surfactants (CTAB—Brij35, SD6 — Brij35, CTAB — BHMI, SDS —BHMI, Brtj35—BHMI) and functional molecule 1—benzyl—2—hydroxymethylimidazole (BHMI) solutions with analog thermogram method of thermokinetics. The kinetic parameters kmIn micellar pseudophase, rate constant kein functional molecular solution, and the association constant of reactant with micelle Ki, with functional molecule K, have been calculated from kinetic equations of mixed micellar catalysis in the case of [S]>[M]. The results indicate that all the researched systems exhibit catalytic effect on the reaction. Polarity and local concentration effect were employed to explain these phenomena. A mechanism of catalysis of BHMI and mixed micelles of a surfactant and BHMI was proposed.
