摘要：
The standard molar enthalpy of combustion of cholesterol was measured at constant volume. According to value of ΔrUmθ(−14358.4±20.65 kJ mol−1), ΔrHmθ(−14385.7 kJ mol−1) of combustion reaction and ΔfHmθ(2812.9 kJ mol−1) of cholesterol were obtained from the reaction equation. The enthalpy of combustion reaction of cholesterol was also estimated by the average bond enthalpies. By design of a thermo-chemical recycle, the enthalpy of combustion of cholesterol were calculated between 283.15∼373.15 K. Besides, molar enthalpy and entropy of fusion of cholesterol was obtained by DSC technique.
