Abstract/OtherAbstract:
Substituted uracil herbicides injected into a gas chromatograph react with trimethylanilinium hydroxide to give N-methyl derivatives with good gas chromatographic properties. Maximum methylation is obtained when the molar ratio of methylating reagent to herbicide is ca 4:1. This technique for preparing derivatives provides rapid qualitative and quantitative chromatography of the substances examined. Chromatographic response was linear with increased concentration for the synthetic standard and the on-column product of uracil herbicide. The proposed derivatization method was used to analyze herbicides in formulations. The methyl derivatives were identified spectroscopically.
