A single equation describes all linear thermal models for the heat losses in heat capacity flow calorimeters. This equation is used to correct for heat losses by extrapolating the apparent heat capacity to the zero value of a modified reciprocal flow rate. The method, which does not require an auxiliary pump, has been successfully tested for aqueous sodium chloride solutions to 300.8°C, with the derived apparent molar heat capacities being in agreement with literature values. Aqueous solutions of 2-methylpropan-2-ol (t-butanol) gave anomalous results requiring further investigation. Two other correction methods are both consistent with the new method but apply less generally and require care in the evaluation of the correction factors. |
