Separation process using organic acids and novel organic acids

This invention provides liquid ion exchangers suitable for use in solvent extraction, as well as novel organic acids which exhibit utility for this purpose. Illustrative of inventive organic acids are compounds corresponding to the formula: where R1 and/or R2 is a C2-C11 linear alkyl group and, when...

More Information
Summary:This invention provides liquid ion exchangers suitable for use in solvent extraction, as well as novel organic acids which exhibit utility for this purpose. Illustrative of inventive organic acids are compounds corresponding to the formula: where R1 and/or R2 is a C2-C11 linear alkyl group and, when employed as a liquid ion exchanger, R1 and/or R2 is preferably a C3-C16 branched alkyl group.
