Chemische Eigenschaften
White to light-brown crystalline solid. May be shipped as a concentrate to be mixed with water and used as a spray. Slight phenolic odor.
Verwenden
4-(2,4-Dichlorophenoxy)butanoic Acid is a herbicide.
Definition
ChEBI: A monocarboxylic acid that is butyric acid in which one of the hydrogens at position 4 is replaced by a 2,4-dichlorophenoxy group. A selective post-emergence herbicide.
Allgemeine Beschreibung
Colorless crystals. Slightly corrosive to iron. A chlorinated phenoxy herbicide. Soluble in organic solvents.
Reaktivität anzeigen
2,4-Dichlorophenoxybutyric acid is an organic acid. Neutralizes bases in exothermic reactions. Forms water soluble metal and amine salts. Hard water precipitates the calcium and magnesium salts from aqueous solutions of such salts.
mögliche Exposition
2,4-DB is a chlorophenoxy/arylox- yalkanoic acid selective systemic herbicide used to control annual and perennial broadleaf weeds in many field crops such as alfalfa, peanuts, cereals and soybeans; used as a defoliant. In the plant, the compound changes to 2,4-D and inhibits growth at the tips of stems and roots.
Versand/Shipping
UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous haz- ardous material, Technical Name Required.
Inkompatibilitäten
2,4-DB is a weak organic acid. Keep away from oxidizers, sulfuric acid, caustics, ammonia, aliphatic amines, alkanolamines, isocyanates, alkylene oxides, and epichlorohydrin. Corrosive to iron, aluminum, zinc, and possibly other metals, especially in the presence of moisture.
Waste disposal
Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Consult with environmental regulatory agencies for guid- ance on acceptable disposal practices. Incineration with effluent gas scrubbing is recommended. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office
