The invention provides a process for solubilizing an organic or mineral salt in an organic solvent, said process comprising contacting an organic or mineral salt of the formula A.sup.- M.sup.+, wherein A.sup.- represents a mineral or organic anion and M.sup.+ represents a cation selected from the group consisting of the cation NH.sub.4.sup.+ and its derivatives and the cations derived from the metals of the groups I.sub.A, II.sub.A, III.sub.A, IV.sub.A, V.sub.A, VI.sub.A, VII.sub.A, VIII, I.sub.B, II.sub.B, III.sub.B, IV.sub.B and V.sub.B of the periodic table, with at least one sequestering agent which is soluble in said organic solvent, said sequestering agent having the formula: N[CHR.sub.1 --CHR.sub.2 --O--(CHR.sub.3 --CHR.sub.4 --O).sub.n --R.sub.5 ].sub.3 (I) wherein n is an integer from 0 to 10 inclusive; R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which can be the same or different, are each a hydrogen atom or an alkyl radical having 1 to 4 carbon atoms; R.sub.5 is an alkyl radical having 1 to 12 carbon atoms, a cycloalkyl radical having 3 to 12 carbon atoms, a phenyl radical, a radical of the formula ##STR1## or a radical of the formula ##STR2## and m is an integer from 1 to 12 inclusive. The process makes it possible to utilize the A.sup.- M.sup.+ salt as a reactant in solvents in which such reaction has not heretofore been possible, or to extract the A.sup.31 M.sup.+ salt from a solution containing it.
本发明提供了一种在有机溶剂中溶解有机或矿物盐的过程,该过程包括将公式A.sup.- M.sup.+的矿物或有机阴离子A.sup.-和阳离子M.sup.+(所述阳离子选自周期表的I.sub.A,II.sub.A,III.sub.A,IV.sub.A,V.sub.A,VI.sub.A,VII.sub.A,VIII,I.sub.B,II.sub.B,III.sub.B,IV.sub.B和V.sub.B金属的衍生物以及阳离子NH.sub.4.sup.+及其衍生物)与至少一种可在有机溶剂中溶解的螯合剂接触,所述螯合剂具有以下公式:N[CHR.sub.1 --CHR.sub.2 --O--(CHR.sub.3 --CHR.sub.4 --O).sub.n --R.sub.5 ].sub.3(I),其中n为0至10的整数,R.sub.1,R.sub.2,R.sub.3和R.sub.4可以相同也可以不同,分别为氢原子或具有1至4个碳原子的烷基基团,R.sub.5为具有1至12个碳原子的烷基基团、具有3至12个碳原子的环烷基基团、苯基、公式##STR1##的基团或公式##STR2##的基团,m为1至12的整数。该过程使得可以在此前不可能进行反应的溶剂中利用A.sup.- M.sup.+盐作为反应物,或从含有该盐的溶液中提取A.sup.- M.sup.+盐。
