S°gas | 76.563 | cal/mol*K | N/A | Kharitonov Yu.Ya., 1987 | This value was calculated by statistical mechanical method. Statistically calculated thermodynamic functions of [ Anjaneyulu Y., 1988] (S(300 K)=301.65 and Cp(300 K)=79.23 J/mol*K) seem to be erroneous. Values of S(298.15 K)=316.5 and Cp(298.15 K)=92.2 J/mol*K were calculated from data for related aldehydes and ketones by difference method [ Dorofeeva O.V., 1997].; GT |
