Monte, Manuel J. S. published the artcileVapor pressures, enthalpies and entropies of sublimation of trans-cinnamic acid and of nine methoxy and dimethoxycinnamic acids, HPLC of Formula: 16909-09-4, the publication is Journal of Chemical Thermodynamics (1999), 31(11), 1443-1456, database is CAplus.
The Knudsen mass-loss effusion technique was used to measure the vapor pressure as a function of temperature for trans-cinnamic acid and nine substituted methoxy and dimethoxy cinnamic acids. From the temperature dependence of the vapor pressure, the standard molar enthalpies and entropies of sublimation at 298.15 K were calculated for all the studied compounds using the estimated value ¦¤crgcp,mo = -50 J¡¤K-1¡¤mol-1. The results obtained for trans-cinnamic acid and for the trans-methoxy and trans-dimethoxy cinnamic acids together with literature results for benzoic acid and substituted methoxy and dimethoxy benzoic acids allowed us to derive the correlation: ¦¤crgHmo{T(p = 0.5 Pa)}/(kJ¡¤mol-1) = (0.623 ¡À 0.026)¡¤{T(p = 0.5 Pa)/K} + (-106.3 ¡À 9.4) where T(p = 0.5 Pa) is the temperature at which the equilibrium vapor pressure of each crystalline compound is 0.5 Pa.
