Abstract: The integral heats of solution of Nd(NCS)3·5DMSO in DMSO-H2O at 298.15K havebeen measured using a modified RD-1 heat conducting automatic calorimeter.The results canbe expressed in following equation:ΔH = - 17.95 + 63.42x2 - 320. 09x22 + 820. 65x23 - 523.00x24 where x2 is the mole fraction of H2O in DMSO-H2O.

Key words: neodym, isothiocyanate, dimethylsulphoxide, integral heat of solution
