説明

Ethyl carbamate occurs as colourless or white columnar crystals or granular powder. It is very soluble in water. With heat, ethyl carbamate undergoes decomposition and emits toxic fumes of carbon monoxide, carbon dioxide, and nitrogen oxides. Ethyl carbamate is used as an intermediate in the synthesis of a number of chemical products, for example, pharmaceuticals, in biochemical research and medicine, and as a solubiliser and co-solvent for pesticides and fumigants. Prior to World War II, ethyl carbamate saw relatively heavy use in the treatment of multiple myeloma before it was found to be toxic, carcinogenic, and largely ineffective. However, due to U.S. FDA regulations, ethyl carbamate has been withdrawn from pharmaceutical use. However, small quantities of ethyl carbamate are also used in laboratories as an anaesthetic for animals.

化学的特性

Colorless crystals or white powder; odorless, saltpeter-like taste. Solutions neutral to litmus. Soluble in water, alcohol, ether, glycerol, and chloroform; slightly soluble in olive oil. Combustible.

化学的特性

Urethane is a colorless, almost odorless crystalline solid or powder.

使用

Naturally occurring contaminant in fermented foods, particularly wine, stone-fruit brandies, and bread. This substance is reasonably anticipated to be a human carcinogen.

使用

antiinfective

使用

Intermediate in organic synthesis. In the preparation and modification of amino resins. As solvent, solubilizer and cosolvent for various organic materials. Animal anesthetic in laboratory procedures.

定義

A poisonous flammable organic compound, used in medicine, as a solvent, and as an intermediate in the manufacture of polyurethane resins.

世界保健機関(WHO)

Urethane was formerly used as an antineoplastic agent in the treatment of chronic myeloid leukaemia. It is also a mild hypnotic which has been used as an anaesthetic for veterinary practice. It has been reported to have both a carcinogenic and mutagenic potential. Although urethane continues to be used as an industrial solvent, WHO has no information to suggest that it remains commercially available in pharmaceutical preparations.

一般的な説明

Odorless colorless crystals or white powder. Sublimes readily at 217°F and 54 mm Hg. Cooling saline taste.

空気と水の反応

Water soluble. Aqueous solutions are neutral to litmus .

反応プロフィール

Urethane is incompatible with alkalis, acids, chloral hydrate, camphor, menthol and thymol. Also incompatible with antipyrine and salol. May react with strong oxidizing agents. Liquefies with benzoic acid, resorcinol and salicylic acid. Reacts with phosphorus pentachloride to form an explosive product .

危険性

Toxic by ingestion.

安全性プロファイル

Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. A transplacental carcinogen. Moderately toxic by ingestion, intraperitoneal, subcutaneous, intramuscular, parenteral, and intravenous routes. An experimental teratogen. Experimental reproductive effects. Human mutation data reported. Causes depression of bone marrow and occasionally focal degeneration in the brain. Can also produce central nervous system depression, nausea and vomiting. Has been found in over 1000 beverages sold in the United States. The most heavily contaminated liquors are bourbons, sherries, and fruit brandies (some had 1000 to 12,000 ppb urethane). Many whiskeys, table and dessert wines, brandies, and liqueurs contain potentially hazardous amounts of urethane. The allowable limit for urethane in alcoholic beverages is 125 ppb. It is formed as a side product during processing.Hot aqueous acids or alkalies decompose urethane to ethanol, carbon dioxide, and ammonia. Reacts with phosphorus pentachloride to form an explosive product. When heated it emits toxic fumes of NOx. Used as an intermedate in the manufacture of pharmaceuticals, pesticides, and fungicides. See also CARBAMATES.

職業ばく露

Urethane is used as a chemical intermediate in manufacture of pharmaceuticals; pesticides, and fungicides; in the preparation of amino resins. It may be reacted with formaldehyde to give cross-linking agents which impart wash-and-wear properties to fabrics. It has also been used as a solubilizer and cosolvent in the manufacture of pesticides, fumigants, and cosmetics. It was formerly used in the treatment of leukemia. It occurs when diethylpyrocarbonate, a preservative used in wines, fruit juices, and soft drinks, is added to aqueous solutions.

応急処置

Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

純化方法

Urethane is best purified by fractional distillation, but it can be 20 25 1.4144. sublimed at ~103o/~50mm. It has also been recrystallised from *benzene. Its solubilitiy at room temperature is 2g/mL in H2O, 1.25g/mL in EtOH, 1.1g/mL in CHCl3, 0.67g/mL in Et2O and 0.03g/mL in olive oil. It is a suspected human carcinogen.[Beilstein 3 H 22, 3 IV 40.]

不和合性

Dust may form explosive mixture with air. 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, gallium, perchlorate.

廃棄物の処理

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposal. Controlled incineration (incinerator equipped with a scrubber or thermal unit to reduce nitrogen oxides emissions).
