| Salicylaldoxime Usage And Synthesis |
| Uses | Salicylaldoxime is an organic compound described by the formula C6H4CH=NOH-2-OH and it is the oxime of salicylaldehyde. This crystalline, colorless solid is a chelator and sometimes used in the analysis of samples containing transition metal ions, with which it often forms brightly colored coordination complexes. |
| Elements Extraction | Salicylaldoxime is recognized as a selective precipitant for copper, although it forms water-insoluble chelates with a number of elements. Ingvar Dahl invested the extraction of divalent magnesium, manganese, cobalt, nickel, copper, zinc, cadmium, mercury, and lead with solutions of salicylaldoxime in benzene and the effect of the reagent concentration and particularly the pH of the aqueous phase on the extractability was also studied. The solubility of salicylaldoxime in organic solvents has been utilized in the solvent extraction of carious elements. |
| Chemical Properties | off-white to light beige crystalline powder |
| Uses | As a reagent for copper and nickel. |
| Uses | Salicylaldoxime reacts with several metal ions to give intensively coloured complexes which are insoluble in water. The structure of the copper(II), nickel(II) and palladium(II) complexes is shown in Fig. 14 (structure I), and that of the manganese(II), iron(II), cobalt(II) and zinc(II) complexes in Fig. 14 (structure II). The copper(Il) and palladium(II) salicylaldoxime complexes are of importance from an analytical point of view. The complexes precipitated from aqueous media are easily filterable and washable and are weighed after drying at 100°C. The precipitates are of stoichiometric composition.
The outstanding stabilities of the copper(II) and palladium(II) complexes make the reagent suitable for the selective determination of these metal ions. These two complexes form quantitatively at low pH values where the complexes of other metal ions do not exist.
Besides the gravimetric method, salicylaldoxime is also useful in the volumetric, amperometric and nephelometric determinations of copper and palladium.
Salicylaldoxime gives a black precipitate with VOs~ in media containing sulfuric acid; this is soluble in chloroform to give an orange solution. The reaction is specific for vanadium which can thus be detected by this method in the presence of almost all other metals.
In neutral medium salicylaldoxime reacts with iron(III) to give a red complex which is soluble in water. The reaction is utilized for the detection of micro amounts of iron. |
