| 应用领域 | Uses: Herbicides (benzoylcyclohexanedione herbicides)、For tembotrione (USEPA、OPP Pesticide Code: 012801) ACTIVE products with label matches.、SRP: Registered for use in the U.S. but approved pesticide uses may change periodically and so federal、state and local authorities must be consulted for currently approved uses.、Herbicide、Applied post-emergence to control a wide range of dicotyledonous and moncotyledonous weed species in maize、Use Classification: Herbicides、Environmental transformation -> Pesticides (parent、predecessor)、Methods of Manufacturing: Mesotrione is prepared by reaction of 3-methylmercaptonitrobenzene with acetyl chloride in the presence of aluminum trichloride yielding the corresponding ketone、which is oxidized with sodium oxychloride giving the corresponding 4-methylsulfonyl compound、which in turn is condensed with cyclohexane-1、3-dione to give the corresponding enol ester. The latter is rearranged to the desired product with potassium cyanide in the presence of triethylamine. ... Tembotrione can be synthesized according to the ... procedure for mesotrione but using 2-(2、2、2-trifluoromethoxymethyl)-3-mercaptomethylchlorobenzene.、Formulations、Preparations: Oil dispersion、Composition: Technical is greater than or equal to 94%.、PREMIX PARTNERS: Terbuthylazine、Thiencarbazone-methyl、AE 0172747 Herbicide (Bayer Cropscience LP.) 34.5% Tembotrione、For more Formulations、Preparations (Complete) data for Tembotrione (6 total)、please visit the HSDB record page. |
