Abstract
The standard (p degrees = 0.1 MPa) molar enthalpies of combustion at T = 298.15 K were measured by static bomb combustion calorimetry for li quid N,N-diethylaniline, N,N-dimethyl-m-toluidine, N,N-dimethyl-p-tolu idine, and N-ethyl-m-toluidine. Vaporization enthalpies for N,N-dimeth yl-m-toluidine and N-ethyl-m-toluidine were determined by correlation gas chromatography. Derived standard molar values of Delta(f)H(m) degr ees(g) at 298.15 K for N,N-diethylaniline (62.1 +/- 7.6); N,N-dimethyl -m-toluidine (72.6 +/- 7.3), N,N-dimentyl-p-toluidine (68.9 +/- 7.4), N-ethyl-m-toluidine (30.5 +/- 3.8 kJ . mol(-1)) were obtained.
