Oximes reagents

The phenolic oxime reagents (Section 9.17.4.2) have also been used to recover copper from chloride leach solutions,156...

Formaldoxime, which is commonly used to determine Mn, can also serve as a reagent for nickel since it forms a brown nickel complex (e = 1.84-10" at 473 nm) [26]. Other oxime reagents for determining Ni include 2-hydroxyacetophenone oxime [27], diacetylmonoxime... 

The product itself is useful as a perfumery, agrochemical and stabiliser chemical although its primary usage is in the form of the oxime. Analogues of the series are 2-hydroxy-5-t-nonylacetophenone (Shell SME as the oxime reagent) and 2-hydroxy-5-dodecylbenzophenone referred to earlier (LIX oxime reagent, Henkel). Both these ketoximes serve as copper extractants although less efficient than the aldoxime for this purpose. 2-Hydroxy-5-t-...
