- Abstract
The phase diagrams of the liquid binary system tetradecane-Nd(III) nitrate solvate with tri-n-butyl phosphate [Nd(NO3)3 (TBP)3] and ternary liquid system tetradecane-tri-n-butyl phosphate-Nd(III) nitrate solvate with tri-n-butyl phosphate were studied in the temperature range 298.15-344.85 K. The phase diagrams of the binary and ternary systems contain an area of homogeneous solutions and an area of separation into two liquid phases (I, II). Phases I and II are enriched in tetradecane and Nd(NO3)3 (TBP)3, respectively. With increasing temperature, the areas of separation into two liquid phases in the binary and ternary systems contract. The compositions of the binary and ternary systems in the critical points at different temperatures and their upper critical solution temperatures were determined.
