The standard molar enthalpies of combustion, (298.15K), of high-carbon faaty alochols (tetradecanol, hexadecanol, stearyl alcohol) were obtained by a precise thermal isolation oxygen bomb calorimeter. The values obtained are, respectively, –(9126.39) kJ•mol-1, –(10446.15) kJ•mol-1, and –(11780.49) kJ•mol-1 for tetradecanol, hexadecanol, and stearyl alcohol. It was found that their standand molar enthlpies of combustion increase when the carbon number increases in the substances. There were also good agreement between the experimental and literature results for tetradecanol and tetradecanol. And the standard molar enthalpies of combustion of stearyl alcohol provided necessary thermodynamics basic data. Therefore, these data are available for the exploiting new synthesis method, engineering design and industry production on high-carbon alochols. |
