    Description / Table of Contents: The Influence of Substrate Micellisation on the Rate of Solvolysis of 1-Methylheptyl Methanesulfonate in Dioxane-WaterThe solvolysis rate of 1-methylheptyl mesylate in 25% dioxane-75% H2O was conductometrically determined at 35°C for varying substrate concentrations (c0 = 0.002-0.08 mol/l). The rate constant decreased with increasing concentration in a manner typical of substrate micellisation above the cmc. A phase diagram shows that in this range of concentration the system is passing from the one phase into the two phase region. The implications of this observation for the experimental background of the ion-pair SN2-mechanism proposed by Sneen in 1969 are discussed.
    Notes: Die konduktometrisch bei 35°C bestimmte Solvolysekonstante von 1-Methylheptyl-methansulfonat in 25% Dioxan-75% Wasser sinkt mit steigender Substratkonzentration (c0 = 0.002-0.08 mol/l). Ein Phasendiagramm zeigt, daß in diesem Konzentrationsbereich der Übergang vom einphasigen in den zweiphasigen Bereich erfolgt. Die Bedeutung dieser Beobachtung für die experimentellen Grundlagen des von Sneen 1969 vorgeschlagenen Ionenpaar-SN2-Mechanismus wird diskutiert.
