Add time:07/31/2019    Source:sciencedirect.com

The vapor pressures of benzoylferrocene and 1,1′-dibenzoylferrocene were measured by torsion-effusion technique. The following pressure-temperature equations were derived benzoylferrocene log P(kPa) = 10.75±0.22−(5314±82)/T 1,1′-dibenzoylferrocene log P(kPa) = 9.29±0.24−(4898±91 )/T Second-law treatment of the experimental data yielded the sublimation enthalpies for benzoylferrocene and 1,1′-dibenzoylferrocene: ΔH0sub,298 = 116.3±6.0 kJ mole−1 and ΔH0sub,298 = 109.3±6.0 kJ mole−1 respectively. Thermal functions of these compounds were also estimated.
