2,4,5-트리클로로페녹시아세트산 C화학적 특성, 용도, 생산
화학적 성질
white to light tan odourless solid물리적 성질
Colorless to pale brown, odorless crystals. Odor threshold from water is 2.92 mg/kg (quoted, Keith and Walters, 1992). Metallic taste.용도
It is suitable for plant cell culture tested. Post-emergence herbicide.정의
ChEBI: A chlorophenoxyacetic acid that is phenoxyacetic acid in which the ring hydrogens at postions 2, 4 and 5 are substituted by chlorines.일반 설명
Light tan solid (melting point 153°C). Insoluble in water. Contact may irritate the skin.공기와 물의 반응
Insoluble in water.반응 프로필
2,4,5-Trichlorophenoxyacetic acid is a weak acid. Reacts with organic and inorganic bases to form water-soluble salts and with alcohols to form esters. Incompatible with strong oxidizing agents and strong bases. Can corrode metals, especially if moist. May harm painted surfaces .건강위험
Overexposure to dust by inhalation or ingestion may cause fatigue, nausea, vomiting, lowered blood pressure, convulsions, coma. Dust may irritate eyes and skin.화재위험
Special Hazards of Combustion Products: Toxic hydrogen chloride and phosgene gases may be formed.잠재적 노출
Those engaged in the manufacture, formulation, and application of this herbicide used to control woody and herbaceous weeds. The EPA has issued a rebuttable presumption against registration of 2,4,5-T for pesticide uses, however. The Viet Nam war era defoliant, Agent Orange, was a mixture of 2,4,5-T and 2,4-D.Carcinogenicity
2,4,5-T was not mutagenic in bacterial assays, and it did not induce aneuploidy or somatic mutation in vitro. In vivo it did not cause micronuclei in mice or dominant lethal mutations in mice or rats.운송 방법
UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3345 Phenoxyacetic acid derivative pesticide, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.Purification Methods
Crystallise this herbicide from *benzene. [Beilstein 6 III 721.] (CANCER SUSPECT)비 호환성
The aqueous solution is a weak acid. Incompatible with sulfuric acid, bases, ammonia, aliphatic amines; alkanolamines, isocyanates, alkylene oxides; epichlorohydrin; strong oxidizers, such as chlorine, bromine, fluorine, and strong bases.폐기물 처리
Two disposal procedures have been discussed for 2,4,5-T: (1) Mix with excesssodium carbonate, add water and let stand for 24 hours before flushing down the drain with excess water; and (2) pour onto vermiculite and incinerate with wood, paper, and waste alcohol. 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. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.2,4,5-트리클로로페녹시아세트산 준비 용품 및 원자재
