The thermodynamic properties of 2-methylaniline and trans-(R,S)-decahydroquinoline

Thermochemical study of the ortho interactions in alkyl substituted anilines

“…The uncertainties of the interactions are suggested to be only equal to those of the experimental f H o m (g) of the alkyl-anilines. e The buttress effect from interactions of alkyl substituents and the NH 2 group in alkyl-anilines: (24) Aliphatic amines (27) Aromatic amines (27) i /(kJ · mol −1 ) CH 3 (29) f H o m (g) of gaseous species is based on the additivity of group properties. The concept of strain (23) and strain energy provides a basis that helps to correlate the structures, stabilities, and reactivities of molecules.…”

“…A nitrogen stream was passed through the U-tube at constant temperature (±0.1 K), and the transported amount of material was collected in a cold trap. A nitrogen flow of (0.28 to 0.56) cm 3 · s −1 was found to be optimal in achieving saturation of the carrier gas at TABLE 1. Formula, density ρ(T = 293 K), massic heat capacity c p (T = 298.15 K), and expansion coefficients (δV /δT ) p of the materials used in the present study …”

“…(Carlo Erba Fraktometer Vega Series GC 6000) and Hewlett Packard Integrator 3390A (N 2 -flow of 0.333 cm 3 · s −1 , SE-30 capillary column of length 25 m). The standard temperature programme of the g.l.c.…”

“…Only a few species of this type have been characterized thermochemically. (2)(3)(4) This paper extends our previous studies (5)(6)(7)(8)(9) on the systematic investigation of a series of substituted benzenes. The aim of this work was an experimental study of the thermochemical properties of alkylanilines at T = 298.15 K (figure 1) with a view to answering the following questions.…”

Thermodynamic properties of pyridine—I. Vapor pressures, high-temperature heat capacities, densities, critical properties, derived thermodynamic functions, vibrational assignment, and derivation of recommended values

“…(29) This formulation for third virial coefficients was applied successfully in analyses of the thermodynamic properties of benzene and methylbenzene, (13) and 2-methylaniline. (30) Uncertainties in the virial coefficients were assumed to be 10 per cent. Derived enthalpies of vaporization are reported in table 7.…”
