金属抽出のための組成物および抽出方法

Japanese Patent JP4885391

B2

A solvent extraction composition is provided which comprises one or more orthohydroxyarylaldoxime or orthohydroxyarylketoxime and at least one dialkyl ester of an optionally substituted ethylene or polyethylene glycol and preferably a water immiscible organic solvent. The orthohydroxyarylaldoximes, or orthohydroxyarylketoximes commonly are of Formula (1),wherein R<1 >is hydrogen or a hydrocarbyl group, and R<2 >is an ortho-hydroxyaryl group; and the dialkyl esters of an optionally substituted ethylene or polyethylene glycol commonly are of Formula (2),wherein R<7 >and R<8 >are each independently an optionally substituted alkyl group; R<9 >to R<20 >are each independently hydrogen or optionally substituted hydrocarbyl; m, n and p are each independently 0, 1, 2, 3 or 4 provided that m+n+p is greater than or equal to 1; and q is 1, 2 or 3. Preferred orthohydroxyarylaldoximes are 5-(C9 to C14alkyl)-2-hydroxybenzaldoximes and preferred orthohydroxyarylketoximes are 5-(C9 to C14alkyl)-2-hydroxyacetophenone oximes. Preferred dialkyl esters of an optionally substituted ethylene or polyethylene glycol are branched dialkyl esters comprising from 10 to 100 carbon atoms, wherein R<7 >or R<8 >are branched alkyl groups. Processes for the extraction of metal values from aqueous acidic and ammoniacal solutions are also provided.
