Abstract

Synthesis of 4-Alkoxy-2-hydroxyphenyl Ketoximes as Reagents for Metal Extraction.-Friedel-Crafts acylation of resorcinol (I) with the acyl chlorides (II) forms the 2,4-dihydroxyphenyl ketones (III). They are converted to the monoethers (V) and subsequently to the oximes (VI). Various other derivatives of (III), (V), and (VII) are described in the original paper. The extraction properties of some oximes for copper(II)-and iron (III)-ions are measured. -(BEGER, J.; BINTE, H.-J.; BRUNNE, L.; NEUMANN, R.; J. Prakt. Chem./Chem.-Ztg. 334 (1992) 3, 269-277; Inst.
