使用
Phenmedipham is an carbanilate selective herbicide used post-emergence in beet crops after the emergence of most broad-leaved weeds and before they develop.
定義
ChEBI: A carbamate ester that is (3-methylphenyl)carbamic acid in which the hydrogen of the hydroxy group has been replaced by a 3-[(methoxycarbonyl)amino]phenyl group.
一般的な説明
Colorless crystals or white powder.
空気と水の反応
Insoluble in water.
反応プロフィール
3-((Methoxycarbonyl)amino)phenyl (3-methylphenyl)carbamate is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates. 3-((Methoxycarbonyl)amino)phenyl (3-methylphenyl)carbamate is incompatible with alkaline preparations.
火災危険
Flash point data for 3-((Methoxycarbonyl)amino)phenyl (3-methylphenyl)carbamate are not available, however 3-((Methoxycarbonyl)amino)phenyl (3-methylphenyl)carbamate is probably combustible.

環境運命予測
Soil. Phenmedipham degraded in soil forming methyl N-(3-hydroxyphenyl)-carbamate
and m-aminophenol (Hartley and Kidd, 1987). Hydrolysis yields m-aminophenol (Rajagopal et al., 1989). The reported half-life in soil is approximately 20 days (Rajagopal et
al., 1989) and 26 days (Worthing and Hance, 1991)
Plant. In plants, methyl N-(3-hydroxyphenyl)carbamate is the major metabolite (Hartley and Kidd, 1987)
Photolytic. Bussacchini et al. (1985) studied the photolysis (λ = 254 nm) of phenmedipham in ethanol, ethanol/water and hexane as solvents. In their proposed free radical
mechanism, homolysis of the carbon-oxygen bond of the carbamate linkage ga

不和合性
Decomposes .145C. Esters ith acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Carbamates are incompatible with reducing agents, strong acids, oxidizing acids, peroxides, and bases. Contact with active metals or nitrides cause the release of flammable, and potentially explosive, hydrogen gas. Releases oxides of nitrogen and carbon when heated to decomposition.
廃棄物の処理
Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Incineration with effluent gas scrubbing is recommended. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
