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⊿E_c~0,分别为-3062.06±o.42,-19,765.64±1.86-3,4s6.72±2.21kJ mol~(-1),利用上述数据和CO_2(g),HO(1)和[HCl.600H_2O](1)的标准生成热,导出此三种化合物的生成热⊿H_±~0分別为-420.71±1.16,-861.97±5.89和189.57±4.59kJ mol_(-1)。
This paper describes the establishment of precision adiabatic and thermostatic dual-purpose rotary bomb calorimeter, and uses the high-purity benzoic acid made by our laboratory to calibrate the energy equivalent of the calorimeter with the precision of 0.02% under adiabatic and constant temperature conditions respectively 0.007%, using this instrument measured p-chlorobenzoic acid, squalane and perchlorophthalonitrile combustion heat value ⊿ E_c ~ 0, respectively -3062.06 ± o.42, -19,765.64 ± 1.86-3,4s6.72 ± 2.21 kJ mol ~ (-1). Using the above data and the standard heat of formation of CO 2 (g), HO (1) and [HCl.600H 2 O] (1) -420.71 ± 1.16, -861.97 ± 5.89 and 189.57 ± 4.59 kJ mol -1, respectively.
