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]
Diethyl thiourea is the inhibitor of corrosion in metal pick/ing solutions; accelerator for mercaptan-modified chloroprene rubber; antidegradant for
natural, nitrile-butadiene, styrene-butadiene, and chloroprene rubbers | [Flammability and Explosibility]
Nonflammable | [Purification Methods]
Crystallise it from *benzene. [Beilstein 4 H 118, 4 I 355, 4 II 610, 4 III 220, 4 IV 375.] |
