一种精密恒温环境微量燃烧-溶解-反应多用量热计的设计及应用
Design and Application of a Precise Isoperibol Combustion-Solution-Reaction Microcalorimeter
摘要
Abstract
The SRC-100 type solution-reaction calorimeter was improved to a more precise and versatile isoperibol combustion-solution-reaction microcalorimeter.The energy equivalent of the calorimeter was calibrated to be Ccalor =(987.63 ± 0.61) J·K-1 by the electric calibration method.The standard massic energy of combustion of benzoic acid and succinic acid were determined by the developed isoperibol combustion-solution-reaction microcalorimeter as ΔcUθm,a(cr,T =298.15 K) =-(26425.99 + 10.70) J·g-1 and ΔcUθm,s(cr,T =298.15 K) =-(12621.97 + 5.30) J·g-1,respectively.The uncertainty of the measurement was less than 0.04％ and the accuracy was higher than 0.05％.关键词
