2,4-D isooctyl ester Chemical Properties,Usage,Production

Chemical Properties

2,4-Dichlorophenoxyacetic acid is a white to yellow crystalline powder with a slight phenolic odor.

Uses

2,4-D isooctyl ester is a useful biochemical for proteomics research.

General Description

White crystals in commerce, a brown or dark brown liquid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

Fire Hazard

2,4-D isooctyl ester is combustible.

Potential Exposure

2,4-Dichlorophenoxyacetic acid, was introduced as a plant growth-regulator in 1942. It is registered in the United States as a herbicide for control of broadleaf plants and as a plant growth-regulator. Thus, workers engaged in manufacture, formulation or application are affected, as may be citizens in areas of application. The Vietnam war era defoliant, Agent Orange, was a mixture of 2,4-D and 2,4,5-T.

Shipping

UN3345 Phenoxyacetic acid derivative pesticide, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials. A DOT regulated marine pollutant.

Incompatibilities

A weak acid, incompatible with bases. Decomposes in sunlight or heat, forming hydrogen chloride and phosgene. Contact with strong oxidizers may cause fire and explosions.

Waste Disposal

Incineration of phenoxys is effective in 1 second @ 982 C, using a straight combustion process or @ 482℃ using catalytic combustion. Over 99% decomposition was reported when small amounts of 2,4-D were burned in a polyethylene bag. See “References” for additional detail. In accordance with 40CFR165, follow (31); recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by follow- ing (100) Package (2) label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. Consult with environ- mental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regu- lations governing storage, transportation, treatment, and waste disposal.
