CARBETAMIDE Chemical Properties,Usage,Production
Chemical Properties
Carbetamide is a colorless, crystalline powder, or solid.
Uses
Carbetamide is used in the determination of pesticides.
Definition
ChEBI: A carbamate ester obtained by the formal condensation of phenylcarbamic acid with the hydroxy group of N-ethyl-2-hydroxypropanamide.
Potential Exposure
Carbamate herbicide used to kill unwanted plants
Metabolic pathway
Photodegradation of carbetamide in solution with UV
irradiation in the presence of UV ? H2O2 and ? TiO2
primarily occurs at the o- and p-positions, but not at
the m-position of the phenyl ring, and the preferential
photoproduct isolated is ortho-hydroxylated
carbetamide. 5-Methyl-3-phenyl-oxazolidine dione is
isolated only in the presence of TiO2. The cyclization
may result from radical coupling with the dissolved
oxygen. N-De-ethylation of the ethylcarbamoyl group
and hydroxylation on the carbamoyloxy linkage occur
to yield free amine of carbetamide and lactamide
analogs. It is interesting to note that formulated
carbetamide is phototransformed to N-ethyllactamide-
4-aminobenzoate as a major product via the
rearrangement reaction similar to the Photo-Fries
reaction. The degradation kinetics of carbetamide and its
potential metabolites are measured at different
temperatures in both unsterilized and sterilized alkaline
soil.
The chemical degradation of carbetamide
importantly gives N-phenyl-3-methyloxazolidine-2,5-
dione which results in 2-(phenylcarbamoyloxy)-
propionic acid and N-phenyl-2-hydroxypropionamide
and the aniline in the soil. The purely biological
degradation of this compound cannot clearly yield
degradation products that are different from those by
chemical degradation in non-sterilized soils.

Incompatibilities
Slowly hydrolyzes in water, releasing ammonia and forming acetate salts. Carbamates are incompatible with reducing agents, strong acids, oxidizing acids, peroxides, and bases. Contact with active metals or nitrides cause the release of flammable, and potentially explosive, hydrogen gas. Amides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides with strong reducing agents such as hydrideds and active metals. Amides are very weak bases (weaker than water). Mixing amides with dehydrating agents such as phosphorus pentoxide or thionyl chloride generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx). This compound is decomposed by strong base or acid.
Waste Disposal
Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved land fill. Consult with environmental regulatory agencies for guidance 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.
