The standard (pdegrees = 0.1 MPa) molar enthalpies of combustion in oxygen of three crystalline N-benzoylthiocarbamic-O-alkylesters, PhCONHCSOR, R = Et (Hbtcee), n-Bu (Hbtcbe), n-Hex (Hbtche), were measured at T = 298.15 K by rotating bomb calorimetry. The standard molar enthalpies of sublimation of the three compounds were measured using Calvet microcalorimetry. These values were used to derive the standard molar enthalpies of formation of the compounds in their crystalline and gaseous phases, respectively.[GRAPHIC](C) 2004 Elsevier Ltd. All rights reserved.
