本文叙述了精密绝热、恒温两用转动弹量热计的建立,并用本实验室自制的高纯度苯甲酸标定了量热计的能当量,其精密度在绝热和恒温条件下分别为0.02%和0.007%,利用此仪器测得对氯苯甲酸、鲨烷和全氯间苯二腈的燃烧热值⊿Ec0,分别为-3062.06±0.42,-19,765.64±1.86-3,4s6.72±2.21kJmol-1,利用上述数据和CO2(g),H2O(1)和[HCl·600H2O](1)的标准生成热,导出此三种化合物的生成热⊿Hi0分別为-420.71±1.16,-861.97±5.89和189.57±4.59kJmol-1.

A precision rotating-bomb combustion valorimeter has been vonstruoted in this laboratory. It can be used for measurements under isothermal jacket condition as well as under adiabatic condition. The calorimeter has been calibrated with benzoic acid prepared and its heat of combustion under standard bomb conditions determined electrically in this laboratory.
