Alachlor Chemical Properties,Uses,Production
Description
Alachlor is a herbicide. Occupational contact dermatitis was rarely observed in agricultural workers.
Chemical Properties
Alachlor is a colorless to yellow crystal chemical substance. It is soluble in most organic solvents, but sparingly in water. Alachlor is an RUP, therefore it should be purchased and used only by certified, trained workers and plant protection applicators. The US EPA categorizes it as toxicity class III, meaning slightly toxic. However, alachlor products bear the signal word danger on their labels because of their potential to cause cancer in laboratory animals. Alachlor is an aniline herbicide used to control annual grasses and broadleaf weeds in field corn, soybeans, and peanuts. It is a selective systemic herbicide, absorbed by germinating shoots and roots. It works by interfering with a plant's ability to produce protein and by interfering with root elongation. Alachlor has extensive use as a herbicide in the United States. It is available as granules or emulsifiable concentrate.
Uses
Alachlor is used pre- or early post-emergence to control annual grasses and many broadleaved weeds mainly in maize, but also in cotton, brassicas, oilseed rape, peanuts, radish, soy beans, and sugar-cane.
Definition
ChEBI: An aromatic amide that is N-(2,6-diethylphenyl)acetamide substituted by a methoxymethyl group at at the nitrogen atom while one of the hydrogens of the methyl group has been replaced by a chlorine atom.
General Description
Crystalline solid. Melting point 104-106°F (40-41°C). Used as a herbicide.
Air & Water Reactions
Hydrolyzes under strongly acidic and strongly basic conditions.
Reactivity Profile
A halogenated acetamide. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
Health Hazard
Alachlor is a slightly toxic herbicide. It causes slight to moderate degrees of skin irritation. While a 90-day study on laboratory rats and dogs given diets containing low to moderate amounts of alachlor (1–100 mg/kg/day) showed no adverse effects, a 1-year study indicated that at a dose above 1 mg/kg/day, alachlor causes damage in the liver, spleen, and kidney.
Agricultural Uses
Herbicide: A pre-emergence herbicide for corn, soybeans, and peanuts, and other field crops. It is a selective systemic herbicide, absorbed by germinating shoots and by roots. It works by interfering with a plant's ability to produce protein and by interfering with root elongation. It is available as granules or emulsifiable concentrate. Alachlor is used in mixed formulations with atrazine, glyphosate, trifluralin, and imaquin. Not approved for use in the EU. A U.S. EPA restricted Use Pesticide (RUP).

Contact allergens
Alachlor is a herbicide. Occupational contact dermatitis was rarely observed in agricultural workers.
Safety Profile
Moderately toxic by ingestion, skin contact, and possibly other routes. Questionable carcinogen with experimental carcinogenic data. Human mutation data reported. When heated to decomposition it emits very toxic fumes of Cland NOx.
Potential Exposure
A chloracetanilide herbicide. In manufacture, formulation and application of this preemergence herbicide, personnel may be exposed. Its major use (99%) is as a preemergence herbicide for field crops (corn, soybeans, and peanuts, etc.).
Environmental Fate
Alachlor dissipates from soil mainly through volatilization, photodegradation, and biodegradation. Many metabolites have been identified; diethylaniline, detected in some soil studies, interacts rapidly with humic substances in the soil. A half-life in soil of 7-38 days has been reported. Under certain conditions, alachlor can leach beyond the root zone and migrate to groundwater.
Shipping
UN2588 Pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.
Incompatibilities
Incompatible 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, epoxides. Corrosive to iron and steel.
Waste Disposal
This compound is hydrolyzed under strongly acid or alkaline conditions, to chloroacetic acid, methanol, formaldehyde and 2,6-diethylanilne. Incineration is recommended as a disposal procedure. Techniques for alachlor removal from potable water have been reviewed by EPA but the data revealed no superior method. Improper disposal of pesticides is a violation of federal law. Dispose In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers.
