    A Kinetic Study of the Thermal Loss of Ethylene from in Supercritical Fluid Solvents


    JC Linehan, CR Yonker, JT Bays, and ST Autrey. J. Am. Chem. Soc., in press.

    Abstract: The thermal loss of ethylene from (Cp in h5-cyclopentadienyl) in supercritical fluid ethylene and supercritical CO2 has been investigated by FTIR spectroscopy over the temperature range from 25°C to 80°C and the pressure range from 172 to 689 bar. The observed rate of ethylene loss from was found to follow first order kinetics and can be described by log k(s-1) = (15.3 ±0.3)-(23.7±0.4 kcal/mol/0(0=2.303 RT).
