from
in Supercritical Fluid Solvents

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).
