THE ACTION OF UNSATURATED CYANOLACTON ON Η$_2$Ο$_2$+ΗΟΟ$^−$ REACTION RATE IN ABSENCE AND PRESENCE OF MICELLES

Abstract

Using gasometric method at 303 K the action of 2-cyano-3,4,4-trimethyl-2-butene-4-olid unsaturated lacton on the Η$_2$Ο$_2$ + ΗΟΟ$^-$ reaction rate has been studied . Taking into consideration the fact that the mentioned lacton is oilsoluble its water-ethanol solutions, as well micellar systems obtained making use two kinds of surfactants: C₁₂H₂₅SO⁻₄Na⁺ and C₁₂H₂₅ N⁺(CH)₃Cl⁻. It has been established that in lacton absence: 

− EtOH decreases the reaction rate (R), but in presence of lacton there is some increase in R value. This phenomenon is discussed in detail.

− In micellar systems the lacton action is similar. There is one difference. After some increase in micelles concentration the reaction rate in lacton presence becomes lower than the R value, determined in lacton absence. This regularity is also discussed in detail, as well as the RNO^• action.
