CYCLOATE

Chemical Properties

Cycolate is an oily, clear, or amber to yellow liquid. Aromatic odor;

Uses

Herbicide used to control several broad-leaved weeds and many annual grasses in sugar beets, table beets and spinach

Definition

ChEBI: Cycloate is a primary aliphatic amine.

General Description

Colorless liquid with an aromatic odor. Used as a selective systemic herbicide.

Air & Water Reactions

Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids or alkalis.

Reactivity Profile

CYCLOATE is a thiocarbamate ester. Flammable gases are generated by the combination of thiocarbamates and dithiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates and dithiocarbamates are incompatible with acids, peroxides, and acid halides.

Flammability and Explosibility

Non flammable

Agricultural Uses

Herbicide: Used to control broadleaf weeds, annual and perennial grasses and nutgrass in spinach, beets, and sugar beets. Not approved for use in EU countries. Actively registered in the U.S.

Trade name

ETSAN®; EUREX®; R-2063®; RO- NEET®; RO-NEET®-6E; RO-NEET® 10G; RONIT®; SABET®

Potential Exposure

Cycolate is a thiocarbamate herbicide used to control broad leaf weeds, annual and perennial grasses and nutgrass in spinach, beets, and sugar beets.

Environmental Fate

Soil. The reported half-life in soil is approximately 4–8 weeks (Hartley and Kidd, 1987)
Groundwater. According to the U.S. EPA (1986) cycloate has a high potential to leach to groundwater
Plant. Cycloate is rapidly metabolized in sugarbeets to carbon dioxide, ethylcyclohexylamine, sugars, amino acids and other natural constituents (Humburg et al., 1989)
Chemical/Physical. In the gas phase, cycloate reacts with hydroxyl and NO3 radicals but not with ozone. With hydroxy radicals, cleavage of the cyclohexyl ring was suggested leading to the formation of a compound tentatively identified as C2H5(CHO)NC(O)SC2H5. The calculated photolysis lifetimes of cycloate in the troposphere with hydroxyl and NO3 radicals are 5.2 hours and 1.4 days, respectively (Kwok et al., 1992).

Incompatibilities

Cycolate reacts violently with powerful oxidizers such as calcium hypochlorite. Thiocarbamate esters are combustible. Poisonous gases are generated by the thermal decomposition of thiocarbamate compounds, including carbon disulfide, oxides of sulfur, oxides of nitro- gen, hydrogen sulfide, ammonia, and methylamine. Thio and dithiocarbamates slowly decompose in aqueous solu- tion to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids. Flammable gases are generated by the combination of thio- carbamates with aldehydes, nitrides, and hydrides. Thiocarbamates are incompatible with acids, peroxides, and acid halides.

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.
