Ethylene thiourea Usage And Synthesis

Chemical Properties

A white powder.

Chemical Properties

Ethylene thiourea is a white to light green, needle-like crystalline solid with a faint amine odor

Uses

elastomer accelerator;chlorinated polyethylene (CPE) rubber vulcanizing accelerator agent

Uses

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.

Uses

Accelerator in synthetic rubber production.

General Description

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.

Reactivity Profile

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.

Hazard

Questionable carcinogen.

Fire Hazard

Ethlenethiourea is combustible.

Contact allergens

Ethylenethiourea, a thiourea derivative, is a rubber chemical. It caused contact dermatitis mainly in rubber workers.

Potential Exposure

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

Carcinogenicity

Ethylene thiourea is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

Shipping

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required

Purification Methods

Crystallise it from EtOH or amyl alcohol. [Beilstein 24 III/IV 22.]

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, epoxides, acid anhydrides, and acrolein

Waste Disposal

Incineration in a furnace equipped with afterburner and scrubber.
