概要
- 論文の詳細を見る
Some isoxazole herbicides were determined by a colorimetric method with p-dimethyl-aminocinnamaldehyde (DACA) as the reagent. The compounds (2,3 and 4) having various substituents at the 3-position were hydrolyzed to 3-amino-5-tert-butylisoxazole (5). The assay method was based on the coloration of 5 with DACA, which was reported previously. The optimum hydrolysis conditions were determined. Compound 5 was obtained from 2,3 and 4 with sufficient recoveries under neutral, alkaline and acidic conditions, respectively. The raw materials could thus be evaluated effectively by simple assay methods.
