摘要: 元素有机物要达到完全的燃烧应当在转动弹量热计中进行,这种量热计与静止弹量热计比较有许多优点。首先,转动的结果起到了对弹液的搅拌作用,使弹内各部分溶液的浓度很快达到平衡。其次,促进了燃烧过程中某些副反应的进行,从而短期获得稳定的反应终态,使燃烧热测量的精度显著提高。

Abstract: Aprecision rotating-bomb calorimeter was calibrated in this laboratory. The energy equivalent of the calorimeter was calibrated by benzoic acid of purity 99.999 mol percent, which was determined in the laboratory of the Institute of Measurement Science of China. The precision of the results of the calibration experiments was expressed in s.d.m. equal to 0.13%.Using this calorimeter, the heat of combustion -△Eco of p-Chlorobenzoic acid was determined to be 3070,8 ±11 KJ/mol.
