메빈포스 화학적 특성, 용도, 생산

• 개요

  Pure mevinphos is a colourless liquid, while technical grade mevinphos is a pale yellow liquid with a very mild odour. It is soluble in water but very soluble in alcohols, ketones, chlorinated hydrocarbons, aromatic hydrocarbons, and many organic solvents. It is both an insecticide and acaricide. The U.S. EPA grouped mevinphos as an RUP, and hence it should be purchased and used only by certified and trained pesticide applicators. It is not registered for use in many countries including the United States. Mevinphos is used to control a broad spectrum of insects, including aphids, grasshoppers, leaf-hoppers, cutworms, caterpillars, and many other insects on a wide range of field, forage, vegetable, and fruit crops. It is also an acaricide that kills or controls mites and ticks. It acts quickly both as a contact insecticide, acting through direct contact with target pests, and as a systemic insecticide, which becomes absorbed by plants on which insects feed.

• 화학적 성질

  Mevinphos is a pale yellow to orange highboiling liquid. Weak odor. The carrier solvent may change the physical properties listed here.

• 용도

  Mevinphos is a pesticide used in the protection of crops. Insecticide.

• 일반 설명

  Pale yellow to orange liquid, with a weak odor. Used as an insecticide and acaricide on vegetables, alfalfa, deciduous fruits and nuts.

• 공기와 물의 반응

  Hydrolyzes rapidly as MEVINPHOS dissolves in water.

• 반응 프로필

  Organophosphates, such as MEVINPHOS, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

• 위험도

  Toxic by ingestion, inhalation, and skinabsorption; use may be restricted; cholinesteraseinhibitor. Questionable carcinogen.

• 건강위험

  MEVINPHOS is super toxic; the probable oral lethal dose for humans is less than 5 mg/kg, or a taste (less than 7 drops) for a 150-lb. person. It has direct and immediate effects whether it is swallowed, inhaled, or absorbed through the skin.

• 화재위험

  Fire may produce irritating or poisonous gases. Runoff from fire control may give off poisonous gases and also cause pollution. When heated to decomposition, MEVINPHOS emits toxic fumes of phosphorus oxides. Avoid strong oxidizers. Avoid temperatures above 77-86F, sources of heat, fire, free flames or spark-generating equipment.

• 농업용

  Insecticide, Acaricide: Mevinphos is an organophosphate insecticide used to control a broad spectrum of insects, including aphids, grasshoppers, leafhoppers, cutworms, caterpillars, and many other insects on a wide range of field, forage, vegetable, and fruit crops. It is also an acaricide that kills or controls mites and ticks. It acts quickly both as a contact insecticide, acting through direct contact with target pests, and as a systemic insecticide which becomes absorbed by plants on which insects feed. Not approved for use in EU countries. Not registered for use in the U.S.

• 색상 색인 번호

  Sensitization to mevinphos (also named Duraphos, Phosdrin, and Phosfene), an organophosphate cholinesterase inhibitor that is used as an insecticide, was rarely reported.

• Safety Profile

  Poison by ingestion, inhalation, skin contact, subcutaneous, intravenous, and intraperitoneal routes. Human systemic effects by ingestion: peripheral motor nerve recording changes. An insecticide. When heated to decomposition it emits toxic fumes of POx.

• 잠재적 노출

• 환경귀착

  Plant. In plants, mevinphos is hydrolyzed to phosphoric acid dimethyl ester, phosphoric acid and other less toxic compounds (Hartley and Kidd, 1987). In one day, the compound is almost completely degraded in plants (Cremlyn, 1991). Casida et al. (1956) proposed two degradative pathways of mevinphos in bean plants and cabbage. In the first degradative pathway, cleavage of the vinyl phosphate bond affords methylacetoacetate and acetoacetic acid which may be precursors to the formation of the end products dimethyl phosphoric acid, methanol, acetone and carbon dioxide. In the other degradative pathway, direct hydrolysis of the carboxylic ester would yield vinyl phosphates as intermediates. The halflife of mevinphos in bean plants was 12 hours (Casida et al., 1956). In alfalfa, the halflife was 17 hours (Huddelston and Gyrisco, 1961).
  Chemical/Physical. The reported hydrolysis half-lives of cis-mevinphos and transmevinphos at pH 11.6 are 1.8 and 3.0 hours, respectively (Casida et al., 1956). The volatility half-lives for the cis and trans forms at 28°C were 21 and 24 hours, respectively (Casida et al., 1956). Worthing and Hance (1991) reported that at pH values of 6, 7, 9 and 11, the hydrolysis half-lives were 120 days, 35 days, 3.0 days and 1.4 hours, respectively (Worthing and Hance, 1991).
  Emits toxic phosphorus oxide fumes when heated to decomposition (Lewis, 1990).

• 비 호환성

  Decomposes in heat (below boiling point @ 300℃) producing phosphoric acid and phosphorous oxides fumes. Strong oxidizers may cause release of toxic phosphorus oxides. Organophosphates, in the presence of strong reducing agents such as hydrides, may form highly toxic and flammable phosphine gas. Keep away from alkaline materials. Corrosive to cast iron, some stainless steels and brass. Attacks some forms of plastics, rubber and coatings.

• 폐기물 처리

  Mevinphos is 50% hydrolyzed in aqueous solutions at an unspecified temperature in 1.4 hours at pH 11, 35 days at pH 7; and 120 days at pH 6. Thermal decomposition is rapidly accomplished by lime sulfur. Mevinphos may also incinerated. 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.
