Phase Separation of Ternary Liquid Systems Tetradecane-Cyclohexanone-Lanthanide(III) Nitrate Solvates with Tri-n-butyl Phosphate

The phase separation diagrams of ternary liquid systems tetradecane-cyclohexanone-lanthanide(III) nitrate solvates with tri-n-butyl phosphate {[Ln(NO₃)₃(TBP)₃, Ln is Nd or Sm} at T = 298.15 K were studied.     

Phase Separation in the Systems Constituted by Tetradecane (Hexane,Decane), Tri-n-Butyl Phosphate,and Cerium(III) Nitrate Solvate with Tri-n-Butyl Phosphate

Phase diagrams of ternary liquid systems constituted by tetadecane (hexane, decane), tri-n-butyl phophate, and cerium(III) nitrate solvate with tri-n-butyl phosphate Ce(NO₃)₃(TBP)₃ with phase separation into liquid phases I and II were studied at 298.15 K. Phase I is enriched in the hydrocarbon diluent, and phase II, in Ce(NO₃)₃(TBP)₃. The distribution of components between phases I and II was considered.     

Phase Separation in Ternary Liquid Systems Containing Rare-Earth Metal(III) Nitrate Solvates with Tri-n-butyl Phosphate

Phase diagrams of ternary liquid systems constituted by tetradecane, tri-n-butyl phosphate, and lanthanide(III) nitrate solvates with tri-n-butyl phosphate {[Ln(NO₃)₃(TBP)₃], Ln = La, Pr, Nd, Sm} were studied at 298.15 K. The distribution of the components between the phases under stratification conditions was considered.     

Phase Separation in Ternary Liquid Systems Tetradecane-n-Octanol (or n-Butanol)-Neodymium(III) Nitrate Solvate with Tri-n-Butyl Phosphate

The phase diagrams of ternary liquid systems tetradecane-n-octanol (or n-butanol)-neodymium(III) nitrate solvates with tri-n-butyl phosphate [Nd(NO₃)₃(TBP)₃] at T = 298.15 K were studied. These diagrams contain the fields of homogeneous solutions and the field of separation into two liquid phases (I, II). The distribution of components between these phases is analyzed.     

Effect of Temperature on Phase Separation in Liquid Binary System Constituted by Tetradecane and Samarium(III) Nitrate Solvate with Tri-n-Butyl Phosphate and Ternary System Constituted by Tetradecane,Tri-n-Butyl Phosphate,and Samarium(III) Nitrate Solvate with Tri-n-Butyl Phosphate

The phase diagrams of a binary liquid system constituted by tetradecane and samarium(III) nitrate solvate with tri-n-butyl phosphate and a ternary system constituted by tetradecane, tri-n-butyl phosphate, and samarium(III) nitrate solvate with tri-n-butyl phosphate were studied at 298.15-355.15 K. The distribution of components between the phases was considered. The points of critical compositions of the ternary system at various temperatures and the upper critical temperature of mixing of the binary and ternary systems were estimated.     

Extaction of lanthanide (III) nitrates from aqueous solutions with <Emphasis Type="Italic">n</Emphasis>-octanol

Extraction of lanthanide(III) nitrates (Ln-Gd) with n-octanol was studied at 298.15 K. The extraction isotherms were obtained and mathematically treated.Translated from Zhurnal Prikladnoi Khimii, Vol. 77, No. 9, 2004, pp. 1571–1572.Original Russian Text Copyright © 2004 by Keskinov, Kudrova, Valueva, Pyartman.
