| CYCLOATE Usage And Synthesis |
| 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 | | 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 | Nonflammable | | 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 groundwaterPlant. 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). | | Shipping | UN3082 Environmentally Hazardous substances,
liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous haz-
ardous material, Technical Name Required | | 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. |
