2-(2,4-ジクロロフェノキシ)プロピオン酸 化学特性,用途語,生産方法

• 外観

  白色〜わずかにうすい黄褐色, 結晶〜粉末又は塊

• 溶解性

  アセトンに溶けやすく、水に極めて溶けにくい。

• 用途

  農薬(除草剤、植物成長調整剤)

• 用途

  ジクロルプロップ試験用標準品。

• 農薬用途

  除草剤

• 化学的特性

  2,4-DP is a combustible, colorless to yellowish to tan crystalline solid with a faint phenolic odor

• 定義

  ChEBI: An aromatic ether that is 2-hydroxypropanoic acid in which the hydroxy group at position 2 has been converted to its 2,4-dichlorophenyl ether.

• 一般的な説明

  Yellowish to colorless solid. Soluble in organic solvents. Used as an herbicide.

• 反応プロフィール

  Dichlorprop is an organic acid. Neutralizes bases in exothermic reactions.

• 安全性プロファイル

  Suspected carcinogen. Poison by ingestion. Moderately toxic by skin contact. An experimental teratogen. Other experimental reproductive effects. Mutation data reported. A fumigant. When heated to decomposition it emits toxic fumes of Cl-.

• 職業ばく露

  A phenoxy herbicide

• 環境運命予測

  The average field half-life is 10 days. Microbial degradation and plant uptake account for the short half-life of dichlorprop. Losses due to leaching, photodegradation, and volatilization are minimal.

• 代謝

  Chemical. Dichlorprop and its salts are very stable, but esters readily hydrolyze under acidic and basic conditions.
  Plant. Degradation of the side chain of dichlorprop to form 2,4-dichlorophenol is most common. Dichlorprop may be conjugated to form glucosides, diglucosides, and to a limited extent triglucosides.
  Soil. The degradation pathway of dichlorprop is similar in plants and soils, forming 2,4-dichlorophenol. Evidence indicates that some microbial communities preferentially degrade the R-enantiomer.

• 輸送方法

  UN3345 Phenoxyacetic acid derivative pesticide, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials

• 純化方法

  Crystallise 2,4-DP from MeOH. It is a plant growth substance, a herbicide and is TOXIC. The R(+)-and S(-)-enantiomers have m 124o (from *C6H6) and [] D ±35.2o (c 1, Me2CO). [Beilstein 6 H 189, 6 III 708, 6 IV 922-923.]

• 不和合性

  Dust may form explosive mixture with air. Contact with oxidizers may cause a fire and explosion hazard. The aqueous solution is a weak acid. Attacks many metals in presence of moisture. Compounds of the carboxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water and a salt that may be harmful. Incompatible with arsenic compounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat, toxic and possibly flammable gases), thiosulfates and dithionites (releasing hydrogen sulfate and oxides of sulfur).

• 廃棄物の処理

  In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
