Abstract:
Silica gel column chromatography was used to purify the phoxim technical. It can be characterized by IR spectra and 1H NMR. The content was determined quantitatively by HPLC. The results showed that the best mobile phase was Ethyl acetate-petroleum ether (1:12). IR spectra and 1H sNMR analysis showed that the phoxim was the same as its molecular structure. The purity of the achieved compound by HPLC was 98.6%.
