The enthalpies of combustion and formation of N-propylcyclohexane and six methylethylcyclohexanes.
J Chem Thermodynamics 1970 May; 2(3):399-405
The enthalpies of combustion of n-propylcyclohexane and six isomeric methylethylcyclohexanes were determined by oxygen-bomb combustion calorimetry. The following values are reported for the standard enthalpy of combustion, delta Hoo(298.15 K)/kcal mol-1, of these compounds in the liquid state: n-propylcyclohexane, (-1404.54+/-0.22); 1-methyl-1-ethylcyclohexane, (-1403.89+/-0.22); 1-methyl-cis-2-ethylcyclohexane, (-1404.84+/-0.22); 1-methyl-trans-2-ethylcyclohexane, (-1403.87+/-0.20); 1-methyl-cis-3-ethylcyclohexane, (-1402.33+/-0.26); 1-methyl-cis-4-ethylcyclohexane, (-1404.+/-0.24); and 1-methyl-trans-4-ethylcyclohexane, (-1402.39+/-0.20). Enthalpies of formation in the liquid state were derived and compared with those predicted by the Allen correlation procedure.
