5,8-ジデヒドロ-6,7-ジヒドロジピリド[1,2-a:2',1'-c]ピラジン-5,8-ジイウム 化学特性,用途語,生産方法

• 調製方法

  Diquat is manufactured in the United Kingdom by the oxidative coupling of two molecules of pyridine over a heated Raney nickel catalyst to produce 2,20-bipyridyl, which is reacted with ethylene dibromide in water to give diquat dibromide. It is formulated worldwide in various water-soluble products and in various concentrations, typically 2 lb/gal.

• 定義

  ChEBI: The organic cation formed formally by addition of an ethylene bridge between the nitrogen atoms of 2,2'-bipyridine. Most often available as the dibromide.

• 一般的な説明

  Diquat ion is a yellow crystalline solid dissolved in a liquid carrier. Diquat ion is a water emulsifiable liquid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since Diquat ion is a liquid Diquat ion can easily penetrate the soil and contaminate groundwater and nearby streams. Diquat ion can cause illness by inhalation, skin absorption and/or ingestion. Diquat ion is used as a herbicide.

• 空気と水の反応

  Water soluble. Solutions are stable in neutral and acid solutions; however, they are unstable in alkaline solutions.

• 反応プロフィール

  Diquat ion is light sensitive. Diquat ion can corrode aluminum and other metals.

• 健康ハザード

  INHALATION: No appreciable vapor pressure. Prolonged contact with spray or mist may cause oral and nasal irritation. EYES: Irritation. SKIN: Irritation. INGESTION: Vomiting, diarrhea, general malaise. Possible kidney and liver damage, dyspnea, and pulmonary edema. With large doses there may be tremors or convulsions. OTHER: May be fatal if swallowed, inhaled, or absorbed through skin.

• 火災危険

  Behavior in Fire: Decomposes at high temperature, charring rather than melting or boiling.

• 农业用途

  Herbicide, Desiccant: Diquat or diquat dibromide is a nonselective, quick-acting herbicide and plant growth regulator, causing injury only to the parts of the plant to which it is applied. Diquat is referred to as a desiccant because it causes a leaf or an entire plant to dry out quickly. It is used to desiccate potato vines and seed crops, to control flowering of sugarcane, and for industrial and aquatic weed control in environments such as catfish farms. It is not residual; it does not leave any trace of herbicide on or in plants, soil, or water.

• 発がん性

  Several carcinogenicity studies have been conducted on diquat by the oral route. In a 2-year feeding study at doses as high as 75 mg/kg in mice, and a drinking water study at doses as high as 2.6 mg/L of water in rats, no evidence of tumorigenicity was seen. Similar negative results were reported for diquat in a 2-year feeding study (Hayes, 1991) in rats at dose levels up to 720 mg/kg and in a 2-year drinking water study in mice at doses of 2–4 mg/kg.
