Thermochemistry of Imines - Experimental Standard Molar Enthalpies of Formation
The standard (p degrees = 0.1 MPa) molar enthalpies of formation Delta(f)H(m) degrees(1 or cr) at the temperature T = 298.15K were measured using combustion calorimetry for benzophenone-imine (A), N-methyl-benzaldehyde-imine (B), N-benzyl-benzaldehyde-imine (C), N-benzyl-pivalophenone-imine (D), N-cyclohexyl-(2,4,6-trimethyl)-benzaldehyde-imine (E), N-phenyl-benzaldehyde-imine (F), N-phenyl-4-nitro-benzaldehyde-imine (G), and N-phenyl-benzophenone-imine (H). The standard molar enthalpies of vaporization Delta(l)(g)H(m) degrees or sublimation Delta(cc)(g)H(m) degrees of compounds A to H were obtained from the temperature Variation of the vapour pressure measured in a flow system. Molar enthalpies of fusion Delta(cr)(l)H(m) degrees of solid compounds were measured by d.s.c.
