THE EFFECT OF MIXED MICELLES OF SURFACTANTS ON THE ALKALINE-HYDROLYSIS OF DIMETHYLFORMAMIDE

The alkaline hydrolysis of dimethylformamide has been studied at 40 de grees C in mixed micelles of surfactants (CTAB-Brij35, SDS-Brij35, CTA B--BHMI, SDS-BHMI, Brij35-BHMI) and functional molecule 1-benzyl-2-hyd roxymethylimidazole (BHMI) solutions with analog thermogram method of thermokinetics. The kinetic parameters k(m) in micellar pseudophase, r ate constant k(f) in functional molecular solution, and the associatio n constant of reactant with micelle K-1, with functional molecule K, h ave been calculated fram 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 c oncentration effect were employed to explain these phenomena. A mechan ism of catalysis of BHMI and mixed micelles of a surfactant and BHMI w as proposed.
