ALLIDOCHLOR Usage And Synthesis

Chemical Properties

Amber liquid or granules.Slightly soluble in water; soluble in alcohol, hexane, and xylene.

Chemical Properties

An oily, amber liquid. Slightly irritating odor

Uses

Pre-emergent herbicide.

Uses

Selective preemergence herbicide used to control annual grass weeds and some broad-leaved weeds in maize, millet, soybeans, sorghum, sugarcane, vegetables and ornamentals.

Definition

An amide that modi- fies RNA and protein biosynthesis and inhibits cell division in primary meristems.

General Description

Amber liquid.

Air & Water Reactions

Slightly water soluble.

Reactivity Profile

Corrosive to steel. .

Hazard

Toxic by ingestion. Dry formulations are irritating to eyes and skin.

Fire Hazard

Flash point data for ALLIDOCHLOR are not available. ALLIDOCHLOR is probably not flammable.

Safety Profile

Poison by skin contact. Moderately toxic by ingestion. An herbicide. When heated to decomposition it emits very toxic fumes of Cland NOx. See also ALLYL COMPOUNDS.

Potential Exposure

Acetamide, and organochlorine herbicide, primarily used to control weeds growing in onion crops. Used as a preemergence and postemergence control for most annual grasses and broadleaf weeds on corn, sorghum, lima beans, snap beans, soybeans, cabbage, peas for canning, celery, onions and some fruits and ornamentals. There are no products registered with the United States Environmental Protection Agency revoked all tolerances on July 21, 1999. There are 25 manufacturers worldwide with 6 located in the U.S.

Environmental Fate

Plant. Allidochlor is translocated in plants to chloroacetic acid and diallylamine. The diallylamine is further transformed to carbon dioxide. The acid undergoes further degradation to glycollic acid which breaks down to glyoxalic acid. Glyoxalic acid undergoes further degradation to give formic acid, glycine and carbon dioxide (Cremlyn, 1991)
Chemical/Physical. Emits very toxic fumes of phosphorus oxides and chlorine when heated to decomposition (Sax and Lewis, 1987).

Shipping

UN2996 Organochlorine pesticides, liquid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials. UN2902 Pesticide, liquid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required

Incompatibilities

Oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); strong acids. Slowly hydrolyzes in water, releasing ammonia and forming acetate salts. Compounds of the carboxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water and a salt that may be harmful. Incompatible with arsenic compounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat, toxic, and possibly flammable gases), thiosulfates and dithionites (releasing hydrogen sulfate and oxides of sulfur).

Waste Disposal

Organochlorines may be completely dechlorinated by sodium in isopropyl alcohol. The UN Recommends incineration methods for disposal of organochlorines. 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.
