摘要
用纯度为99.999%的量热基准苯甲酸标定了实验室建立的精密转动弹量热计,其能当量为18604.99±8.14J/K,测得一水合邻菲罗啉(phen·H2O)的燃烧能为-5757.45±2.53kJ/mol,换算成标准燃烧焓为-5759.93±2.53kJ/mol,进而计算出一水合邻菲罗啉的标准生成焓为-391.34±2.98kJ/mol。
A precision rotating-bomb combustion calorimeter in which thermistors were used as the elements of temperature control, and temperature measurement was constructed in the laboratory. The calorimeter was calibrated with benzoic acid with purity of 99.999%. The energy equivalent of standard calorimeter system is 18604.99±8.14 J/K. The combustion energy of 1,10-Phenanthroline hydrate determined in the precision rotating-bomb calorimeter is --5757.45 ±2.53 kJ/mol and the standard enthalpy of combustion is --5759.93 ± 2.53 kJ/mol. The standard enthalpy of formation of phen-H20 calculated is -- 391.34 ± 2.98 kJ/mol.
