SEQUENTIAL THIN-LAYER CHROMATOGRAPHY OF CARBARYL AND RELATED-COMPOUNDS

Sequential thin layer chromatography is performed on silica gel G plates (0.5 mm thick layer) for the separation of carbaryl and related compounds. Common solvents such as benzene, carbon tetrachloride, chloroform, distilled water, 1,4-dioxane, and ethyl acetate are used for sequential development of the plates. Some important separations are: carbaryl from phenol, o-nitrophenol, alpha-naphthol and carbofuran; in carbon tetrachloride followed by distilled water; carbofuran from phenol, o-nitrophenol, alpha-naphthol, carbaryl and beta-naphthoxyacetic acid in distilled water followed by chloroform etc.
