| | DEMETON S Usage And Synthesis |
| Chemical Properties | Oily Liquid | | Chemical Properties | Demeton is a light brown liquid with an odor
of sulfur compounds; freezing/melting point ≤‐13
C | | Uses | Colinesterase inhibitor. Insecticide | | Definition | ChEBI: Demeton-S is an organothiophosphorus compound. | | Safety Profile | Poison by ingestion,
intraperitoneal, and subcutaneous routes.
When heated to decomposition it emits very
toxic fumes of POx and SOx. See also
DEMETON-0 + DEMETON-S and other
demeton entries. | | Potential Exposure | A potential danger to those involved
in the manufacture, formulation, and application of this
systemic insecticide and acaricide. | | Shipping | UN3278 Organophosphorus compound, liquid,

Poisonous materials, Technical Name Required. | | Incompatibilities | May form explosive mixture with air.
Strong oxidizers, strong bases, soluble mercury, other
pesticides, and water. | | Waste Disposal | The thiono-and thiolo-isomers of
this mixture are 50% hydrolyzed in 75 minutes and 0.85 min-
ute, respectively @ 20℃
and pH 13. At pH 9 and 70 ℃
, the
half-life of Demeton is 1.25 hour, but an pH 1-5 it is over
11 hours. Sand and rushed limestone may be added together
with a flammable solvent; the resultant mixture may be burned
in a furnace with afterburner and alkaline scrubber
.In
accordance with 40CFR165, follow recommendations for the
disposal of pesticides and pesticide containers. Must be dis-
posed properly by following package label directions or by
contacting your local or federal environmental control agency,
or by contacting your regional EPA office. |
