Process for the solubilization of organic or mineral salts in organic solvents and complexes of organic or mineral salts

摘要

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-M+, wherein A- represents a mineral or organic anion and M+ represents a cation selected from the group consisting of the cation NH4+ and its derivatives and the cations derived from the metals of the groups IA, IIA, IIIA, IVA, VA, VIA, VIIA, VIII, IB, IIB, IIIB, IVB and VB of the periodic table, with at least one sequestering agent which is soluble in said organic solvent, said sequestering agent having the formula: N[CHR1-CHR2-O-(CHR3-CHR4-O)n-R5]3 (I) wherein n is an integer from 0 to 10 inclusive; R1, R2, R3 and R4, which can be the same or different, are each a hydrogen atom or an alkyl radical having 1 to 4 carbon atoms; R5 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 IMAGE or a radical of the formula IMAGE and m is an integer from 1 to 12 inclusive. The process makes it possible to utilize the A-M+ salt as a reactant in solvents in which such reaction has not heretofore been possible, or to extract the A31 M+ salt from a solution containing it.
