The specific rates of solvolysis of n-Propyl-chloroformatewere measured inseveral hydroxylic solvents at 25.0 ° C. For methanolysis, the solvents were deuterium isotope effect and activation parameters determined and the activation parameters for solvolysis in ethanol and 80% ethanol so determined. For several of the binary n-Propyl-chloroformate, measurement of the product selectivity ratio allows to determine values. Grunwald-Winstein Anextended treatment of the data led to changes in sensitivity to ionizing solventnucleophilicity and power. Comparison with previously determined specific ratesfor solvolysis of chloroformate has is fluorine / chlorine rate of greater than one. Allof the determinations were carried out as part of an addition-elimination (association-dissociation) mechanism, rate-limiting with the addition. Additional specific rates of n-Propyl-chloroformate are determined, to a total of 49 data points, which give simple and extended Grunwald-Winstein treatments areUsed phenyl chloroformate.These values combined with literature values.
