White crystalline powder or crystals · Solubility in water at 20 ° C 1000 g/l · D: 1,67 · M. P.: 151 ° C · pH 0,2 M sol.: 3,2 ·
APPLICATIONS: Analytical reagent · Separation of selenium and tellurium ·
Synthesis reagent: Preparation of oximes · Dehydration of oximes is a valuable route to nitriles. A vast array of reagents have been used: Acetic anhydride . Trifluoroacetic anhydride in pyridine .Trichloroacetyl chloride in triethylamine . Trifluoromethanesulphonic anhydride. Trifluoroacetylimidazole . N,N’-Carbonyldiimidazole . DMF-thionyl chloride complex . Thionyl chloride in the presence of 4-dimethylaminopyridine . Sulphuryl chloride-fluoride · Preparation of oximes from carbonyl compounds. For example: Benzophenone, n-heptanal and veratraldehyde· A large number of reagents have been used for the cleavage of oximes to regenerate the carbonyl compound. Amberlite 15 in acetone/water. Dowex 50 in aqueous suspension . Copper (II) sulphate in THF/water . Ammonium and cerium (IV) nitrate . Alkaline hydrogen peroxide in methanol . Bromine in aqueous solution of sodium hydrogen carbonate· Reagent used for the reductive cleavage of oximes: Titanium (III) chloride in aqueous buffer Tetrahedron Lett. . Vanadium (II) chloride . Sodium meta-bisulphite. Nickel-Raney in acetone-methanol · A number procedures are available for the one-pot conversion of aldehydes to nitriles: In N,N-dimethylformamide. In N-methylpirrolidone. In pyridine-toluene . In formic acid · Ketooximes on treatment with acid catalysts or acylatyng agents undergo the Beckmann rearrangement to amides. · Oxime tosylates undergo the Neber rearrangement to a-aminoketonesin basic conditions. · For other oxime reactions see · The reduction of oximes is a convenient route to primary amines |
