The enthalpy of reaction of tris(hydroxymethyl)aminomethane with 0.1 HCl has been measured using an isoperibol solution calorimeter, employing a modified quartz thermometer and an automatic digital data acquisition system. The enthalpy value obtained at 298.15 K is 245.93 ± 0.26 J · g. Particular attention was given to possible sources of systematic error in the electrical calibrations.
使用等温环境溶液量热计,采用改良的石英温度计和自动数字数据采集系统,测量了三(羟甲基)氨基甲烷与0.1 HCl反应的焓。在298.15 K下获得的焓值为245.93±0.26 J·g。特别关注了电校准中可能存在的系统误差来源。
