The C-Acylation (Friedel-Crafts reaction) of resorcinol with aluminium chloride, the monoetherification in 4-position of the resulting 2,4-dihydroxyphenylketones, and the preparation of oximes (8, 9, 10, 11) from this ketones were investigated.The compounds obtained are characterized by elemental analysis, and the i.r., u.v. and 1H-n.m.r. spectra are discussed.Solubility data of some oximes are determined in water, octane and toluene.The extraction properties for copper-(II)-and iron-(III)-ions are measured by isotope methods in relation to the extragent structure, the extraction time and the pH-range.
