摘要
介绍一种精密滴定热量计,阐述热量计的设计原理,并对其结构进行了详细的阐述。热量计有效反应体积为100mL,恒温槽控温精度为±0.001 K,测温灵敏度为5×10^(-5)K,加样精度为0.5μL。用THAM对仪器进行了标定,测得溶解热为—47567±76J·mol^(-1),与文献值吻合。
A titration calorimeter has been developed. Its design principle and constitu-tion were introduced. Its effective volume of reaction is 100 cm3. The precision of thermostat control temperature system is (?±0. 001 K. The limit of titration volume is 0. 5 μL. We had callibrated the performance of calorimeter with standard referance material THAM,its reac-tion enthalph in 0. 100 0 mol ?L-1 HC1 solution is - 47 567±76J· ?mol-1 at 298. 15 K,which conforms correctly to the literature value.
