데메톤-S-메틸 화학적 특성, 용도, 생산

• 개요

  Demeton-S-methyl is pale yellow in colour and oily and has a sulphur-like odour. It is sparingly soluble in water but very rapidly soluble in common polar organic solvents such as dichloromethane, 2-propanol, toluene, and n-hexane. It is a highly toxic, systemic, and contact insecticide and acaricide and classified as Category I. It is used for the control of insects, aphids, sawflies, and spider mites on cereals, fruits, vegetables, and ornamental plants. On heating, demeton-S-methyl undergoes decomposition and emits very toxic fumes, phosphorus oxides, and sulphur oxides.

On heating, demeton-s-methyl undergoes decomposition and emits very toxic fumes, phosphorus oxides, and sulfur oxides.

• 용도

  Demeton-S-methyl is a systemic insecticide used to control sucking insects and mites in a wide range of crops and ornamentals.

• 일반 설명

  Pale yellow oil. Used as an insecticide. Not registered as a pesticide in the U.S.

• 반응 프로필

  Organophosphates, such as DEMETON-S-METHYL, 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.

• 건강위험

  DEMETON-S-METHYL inhibits the nervous system and is absorbed readily through the skin. DEMETON-S-METHYL is a liquid organophosphorus insecticide. Poisonous; may be fatal if inhaled, swallowed or absorbed through skin. Contact may cause burns to skin and eyes.

• 화재위험

  When heated to decomposition, DEMETON-S-METHYL emits very toxic fumes of oxides of phosphorus and sulfur. DEMETON-S-METHYL is a liquid organophosphorus insecticide. DEMETON-S-METHYL may burn but does not ignite readily. Container may explode in heat of fire. Fire may produce irritating or poisonous gases. Runoff from fire control water may give off poisonous gases. Hydrolyzed by alkali.

• Safety Profile

  Poison by ingestion, inhalation, sh contact, intraperitoneal, and intravenous routes. Mutation data reported. An insecticide. When heated to decomposition it emits very toxic fumes of POx and SOx. See also DEMETON-0 + DEMETON-S and other demeton entries.

• 잠재적 노출

  An organophosphate insecticide. Those engaged in the manufacture, formulation and appli- cation of the insecticide and acaricide on agricultural and horticultural crops.

• 신진 대사 경로

  The initial step for the biotransformation and photolytic activation of demeton-S-methyl is by thiooxidation to oxydemeton-methyl; consequently the metabolism of the two insecticides is very similar and metabolic routes determined for oxydemeton-methyl should be taken as applicable to the behaviour of demeton-S-methyl in the same system. Most studies on the biotransformations of these compounds have used oxydemeton-methyl.

• 저장

  Demeton-S-methyl should be kept stored separately and away from food and feedstuffs. Keep in a well-ventilated room.

• 비 호환성

  ncompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. Strong oxidi- zers 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.

• 폐기물 처리

  The thiono-and thiolo-isomers of this mixture are 50% hydrolyzed in 75 minutes and 0.85 min- ute, respectively @ 20℃ and pH 13. At pH 9 and 70 ℃ , the half-life of Demeton is 1.25 hour, but an pH 1-5 it is over 11 hours. Sand and rushed limestone may be added together with a flammable solvent; the resultant mixture may be burned in a furnace with afterburner and alkaline scrubber .In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be dis- posed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.

• 주의 사항

  During handling and use of demeton-S-methyl, occupational workers should use a face shield or eye protection in combination with breathing protection, protective gloves, and protective clothing. During use and handling of the chemical substance, workers should not eat, drink, or smoke during work and wash hands before eating. Workers should prevent generation of chemical mists and observe strict hygiene.
