摘要
用本实验室建立的精密转动氧弹燃烧热量计测定了标准物质对溴苯甲酸、辅助物质鲨烷及四对溴苯基卟啉(T_(p-Br)PP)的标准燃烧能,并计算出了它们的标准生成焓。
Using precis ion rotating-bomb combustion calorimeter, the standard energies of combustion of squalane, 4-bromobenzoic acid and tetra-(p-bromophenyl)-porphyrin at 298.15 K were determind to be -46.7408±0.0117, -15.3774±0.0063 and -23.4038± 0.0121kJ.g^(-1) respectively. The corresponding standard enthalpies of formation at 298.15 K were calculated to be -864.7±6.4, -377.4±1.6 and 754.2 ±12.6 kJ. mol^(-1). The uncertainties of the results were given twice the final overall standard deviation of mean.
