Chemical Properties
white to buff-coloured solid
Definition
ChEBI: Thiourea in which each nitogen carries an ethyl substituent.
General Description
Buff solid or white powder.
Reactivity Profile
N,N'-DIETHYLTHIOUREA(105-55-5) is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
Air & Water Reactions
This material may be sensitive to exposure to air. . Slightly soluble in water.
Health Hazard
ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits toxic fumes.
Fire Hazard
Flash point data are not available for this chemical, but N,N'-DIETHYLTHIOUREA is probably combustible.
Description
Diethylthiourea, a thiourea derivative, is used mainly
as a rubber chemical, particularly in solid neoprene
products.
Uses
