| | Ethylthiocyanate Usage And Synthesis |
| Chemical Properties | clear colorless liquid | | Chemical Properties | Ethyl thiocyanate is a liquid. Onion odor | | Uses | Ethyl thiocyanate was used in the synthesis of hydrogen cyanide by undergoing in situ reduction with dithiothreitol. | | General Description | Liquid. Used as an agricultural insecticide. | | Reactivity Profile | Nitric acid violently oxidized a thiocyanate solution [Bretherick, 1979 p. 121]. Caution should be exercised in treating a thiocyanate with an oxidizing agent such as a peroxide or chlorate as such mixtures have been known to explode. | | Health Hazard | Ethylthiocyanate is highly toxic if ingested. | | Fire Hazard | When heated to decomposition, Ethylthiocyanate emits very toxic fumes of oxides of nitrogen and sulfur. | | Safety Profile | Poison by ingestion,
subcutaneous, intraperitoneal, and
intravenous routes. When heated to
decomposition it emits very toxic fumes of
NO, and SOx. See also THIOCYANATES. | | Potential Exposure | This thiocyanate material is used as an
agricultural insecticide | | Shipping | UN2929 Toxic liquids, flammable, organic,
n.o.s., Hazard class: 6.1; Labels: 6.1-Poison Inhalation
Hazard, 3-Flammable liquid, Technical Name Required | | Purification Methods | Fractionally distil the ester at atmospheric pressure. [Beilstein 2 IV 1218.] (CARE LACHRYMATOR.) | | Incompatibilities | Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, and epoxides. Esters are generally
incompatible with nitrates. Moisture may cause hydrolysis
or other forms of decomposition. Caution should be exercised in treating a thiocyanate with an oxidizing agent such
as a peroxide or chlorate as such mixtures have been
known to explode | | Waste Disposal | In accordance with 40CFR
165 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 |
