N-Phenylbenzohydroxamic acid Chemical Properties,Usage,Production
Chemical Properties
off-white fibrous powder
Uses
N-Benzoyl-N-phenylhydroxylamine was used as a complexing agent for studying the dispersive liquid-liquid microextraction based on solidification of floating organic drop (DLLME-SFO) behavior of vanadium (V). It was used as an extractant in the determination of beryllium in natural waters.
General Description
The mechanism of the reaction of N-benzoyl-N-phenylhydroxylamine with vanadium(IV) was studied.
Synthesis
100-52-7
586-96-9
304-88-1
The general procedure for the synthesis of N-benzoylphenylhydroxylamine from benzaldehyde and nitrobenzene: the reaction was carried out under the catalytic conditions of different imidazolium and triazolium salts, and it was found that triazolium salts with lower spatial site resistance significantly increased the yield of the product, N-benzoylphenylhydroxylamine (see Table 1). The experimental results showed that the reaction could be carried out efficiently even at catalyst concentrations as low as 0.125 mol%. Table 1 details the reaction conditions for the preparation of N-benzoylphenylhydroxylamine.
Purification Methods
Recrystallise it from hot water, *benzene Et2O/hexane or acetic acid. It complexes with metals. [Beilstein 15 III 8, 15 IV 7.]
