Ethylene thiourea Usage And Synthesis
A white powder.
Ethylene thiourea is a white to light green, needle-like crystalline solid with a faint amine odor
elastomer accelerator;chlorinated polyethylene (CPE) rubber vulcanizing accelerator agent
2-Imidazolidinethione is a pesticide used in production of fruits and vegetables. It is also used as a new contrast agent for MRI studies based on proton chemical exchange dependent saturation transfe r. 2-Imidazolidinethione is also a corrosion inhibitor due to the adsorption of the mol. species.
Accelerator in synthetic rubber production.
White to pale green crystals or an off-white solid. Odorless when pure, but technical product may have an amine odor.
Air & Water Reactions
Slightly soluble in water.
Ethlenethiourea may be sensitive to prolonged exposure to light. Incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. May react with acids to liberate hydrogen sulfide.
Ethlenethiourea is combustible.
Ethylenethiourea, a thiourea derivative, is a rubber chemical. It caused contact dermatitis mainly in rubber workers.
Ethylene thiourea is used extensively as an accelerator in the curing of polychloroprene (Neoprene) and other elastomers; as a vulcanizing accelerator in rubber processing; in electroplating baths. In addition, exposure to ethylene thiourea also results from the very widely used ethylene bisdithiocarbamate fungicides. Ethylene thiourea may be present as a contaminant in the ethylene bisdithiocarbamate fungicides and can also be formed when food containing the fungicides is cooked
Ethylene thiourea is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

Crystallise it from EtOH or amyl alcohol. [Beilstein 24 III/IV 22.]
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, epoxides, acid anhydrides, and acrolein
