PREPARATION, PROPERTIES, AND ANALYTICAL APPLICATIONS OF SOME SUBSTITUTED ALICYCLIC VIC-DIOXIMES

摘要

The application of organic analytical reagents to the determination of metallic ions has progressed rapidly in the last few decades. Many of these organic compounds have proved to be selective in their action and thereby make possible the determination of one or two ions in the presence of several others.nPerhaps one of the most widely used organic reagents for the determination of nickel is 2,3-butanedionedioxime, commonly called dimethyl-glyoxime. This compound and many others possessing the vic-dioxime functional group have been studied extensively in their analytical applications for the determination of both nickel and palladium and while much is known concerning the nature of the nickel(II)- and palladium(II)-dioxime complexes, the knowledge is far from complete.nThe need for better analytical reagents always exists and even though scores of reports on the application of various dioximes to the analysis for nickel and palladium are in the literature, no one dioxime has been shown to possess all of the characteristics of an ideal reagent.
