Ternary systems of rare earth salt-butylamine salt-water

Phase equilibrium in ternary systems, containing water, samarium and dysprosium chlorides, neodymium and gadolinium nitrates and hydrochlorides or nitrates of n-, s-, t-butylamines, were studied at 20(25) and 40(50) def C. The system of gadolinium nitrate-t-butylamine nitrate-water is referred to the systems with chemical interaction of salt components; a new solid phase of the composition 1:2 was detected. The rest systems are referred to the simple eutonic type, their solubility isotherms consist of two non-interlinking branches, charcterizing solubility lines of the initial salt components
