BASIC DEGRADATION OF 3-KETO-CARBOFURAN IN THE PRESENCE OF NON-IONIC SELF-ASSEMBLY COLLOIDS

The effect of non-ionic micellar aggregates upon the stability of 3-keto-carbofuran in basic media has been studied. The presence of non-ionic micelles implies a large inhibition of the basic hydrolysis of 3-keto-carbofuran. This inhibition is due to the association of 3-keto-carbofuran with the mic...

Zusammenfassung:	The effect of non-ionic micellar aggregates upon the stability of 3-keto-carbofuran in basic media has been studied. The presence of non-ionic micelles implies a large inhibition of the basic hydrolysis of 3-keto-carbofuran. This inhibition is due to the association of 3-keto-carbofuran with the micellar core. The kinetic constants for the basic hydrolysis in these microheterogeneous media have been obtained on the basis of a micellar pseudophase model. No significant changes in the intrinsic reactivity of HO against 3-keto-carbofuran have been observed.
