Kinetics of Phenylhydrazine-Glucose Reaction In Anionic and Cationic Surfactant Media

Abstract

Osazone formation by glucose has been shown to occur at room
temperature in the presence of surfactants. ·The kinetics of this
reaction reveal that the rate is increased by both anionic and cationic
swfactants at premicellar concentrations whereas it is retarded at
postmicellar concentrations. Also, in the presence of surfactants,
the reaction depends on the first order on phenylhydrazine but is
zero order with respect to glucose. A mechanism involving adsorption
of phenylhydrazine on surfactant as a slow step followed by a
fast attack by glucose is proposed.
