Abstract
Kinetic analysis confirms that monomeric triethyl-aluminium is the reactive species. Previous ambiguities concerning the rate equation are resolved. The limiting form, –d[RCH : CH2]/dt=k1c½ Al2[RCH : CH2], is attained at high concentration of triethyl-aluminium (cAl2 ) up to 393 K. Arrhenius parameters for k1 are calculated. Two determinations of the equilibrium constant for dissociation of Al2Et6 in hydrocarbon solution indicate a higher extent of dissociation above 363 K than previously supposed. Rate coefficients and Arrhenius parameters for the rate-controlling reactions of monomeric Et3Al on n-1-alkenes have been recalculated on this basis.Keywords
