Paint formulations comprising at least one long oil alkyd resin and a solvent comprising one or more linear alkanes having a boiling range between 160.degree. and 250.degree. C., preferably between 170.degree. and 200.degree. C.

Paint formulations

A process is described for the selective recovery of nickel values from an aqueous solution containing nickel values by means of liquid/liquid extraction, wherein the aqueous solution is contacted with an organic extractant comprising a substantially water-immisicible organic solvent and one or more of certain alpha,beta-dioxime compounds. Novel alpha, beta-dioxime compounds for use in the extraction process are also described.

Liquid/liquid extraction of nickel values

A process is described for the recovery of copper values from an acidic aqueous solution containing copper values by means of liquid-liquid extraction, wherein the extractant is a mixture comprising a substantially water-immiscible organic solvent, one or more hydroxyoximes capable of extracting copper values, and one or more alpha, betadioximes of the anti-configuration. Novel alpha, beta-dioxime compounds are also disclosed.
