Ethylene thiourea Chemical Properties,Uses,Production

Description

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

Chemical Properties

Ethylene thiourea is a white to light green, needle-like crystalline solid with a faint amine odor. It is very soluble in hot water;slightly soluble in cold water, methanol, ethanol, ethylene glycol, pyridine, acetic acid, and naphtha; and insoluble in acetone, ether, chloroform, and benzene.When heated to decomposition, ethylene thiourea emits toxic fumes of nitrogen oxides (NOx) and sulfur oxides (SOx).
Ethylene thiourea
Ethylene thiourea is available in the United States as crystals, as a powder, as an 80% dispersion of the powder in oil, or encapsulated in a matrix of compatible elastomers.

Uses

elastomer accelerator;chlorinated polyethylene (CPE) rubber vulcanizing accelerator agent.
Ethylene thiourea is used primarily as an accelerator for vulcanizing polychloroprene (Neoprene®) and polyacrylate rubbers. Neoprene rubbers are used almost exclusively in industrial applications,e.g.. for mechanical and automotive products, in wire and cable production, in construction,and in adhesives. Polyacrylate rubbers are used in products such as seals, o-rings, and gaskets for automotive and aircraft applications. Ethylene thiourea is used in the manufacture of ethylene-bisdithiocarbamate pesticides, such as Maneb®, Mancozeb®, Metiram®,and Zineb®.Ethylene thiourea is also used in electroplating baths, as an intermediate in antioxidant production, in dyes, pharmaceuticals,and synthetic resins. However, there is no evidence that the compound is used commercially for any of these purposes (IARC V.7, 1974; Sax, 1987).

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.

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

Ethylene thiourea is combustible.

Contact allergens

Ethylene thiourea, 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.
