| Abstract: | Using Reilly and Rae's method,the solubility of TPP-HSO3 has been determined in differential temperature. The solubility and temperature conform with the following equation: Lnm =3.081×10-4 0.0685T + 1.78×10-4 T2With the help of the Van't Hoff equation, the heat of solution is calculated and its relevant equation is as follows:ΔHθ=- 0.5695T2 + 2. 9598×10-3T3 |
