Bromoacetic acid ethyl ester

에틸브로모아세트산 C화학적 특성, 용도, 생산

물성

물에 녹지 않는다. 수산화나트륨 용액에 의해 가수 분해된다. 철과 반응한다. 눈을 강하게 자극함과 동시에 유독성이다.

용도

1) 유기 합성 원료. 2) 독가스(제1차 세계 대전에 최초로 사용된 독가스로, 염소를 사용한 1915년 4월에 앞서 1914년 말에 프랑스군이 가스 유탄으로 사용했다고 한다).

화학적 성질

Ethyl bromoacetate is a clear, colorless to light-yellow liquid and has a pungent odor. It is insoluble in water, but is soluble in acetone and benzene (Lide, 1999; Lewis, 1997). Ethyl bromoacetate is miscible with ethanol, ethyl ether, and with other oxygenated and aromatic solvents (Ashford, 1994; Lide, 1999). It is partially decomposed by water (Lewis, 1997).

용도

Ethyl bromoacetate is widely used as an alkylating reagent involved in the Reformatsky reaction to prepare the beta-hydroxy esters by reacting with carbonyl compounds. It is also used for the syntheses of witting reagent, artificial diethylstilbestrol antigen, 3-phenyl-1-naphthol and steroidal thiazolidinone derivatives. It finds applications in the preparation of reversibly photoresponsive coumarin-stabilized polymeric nanoparticles in an aqueous medium which act as a detectable drug carrier.

용도

Ethyl Bromoacetate, is used in the synthesis of metabolites of carcinogenic PAHs. Used in the preparation of steroidal antiestrogens through cyclic condensation. A reactant in the preparation of antim icrobial and antioxidant coumarinyloxymethyl-thiadiazolone.

일반 설명

A clear, colorless liquid (b.p. 318°F). Flash point 47°C. A lachrymator. Toxic by ingestion, inhalation and skin absorption; a strong irritant of the skin. Insoluble in water and soluble in alcohol, benzene, and ether. Specific gravity of 1.5.

공기와 물의 반응

Flammable. Insoluble in water.

반응 프로필

Ethyl bromoacetate is a halogenated ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

위험도

Toxic by ingestion, inhalation, and skin absorption; strong irritant.

건강위험

TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Bromoacetates and chloroacetates are extremely irritating/lachrymators. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

화재위험

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.

Safety Profile

A poison. An irritant to skin, eyes, and mucous membranes. Questionable carcinogen with experimental neoplastigenic data. Flammable liquid when exposed to heat, flame, and oxidizers. Will react with water or steam to produce toxic and corrosive fumes. To fight fire, use water as a fire blanket. When heated to decomposition or on contact with acid or acid fumes, it emits highly toxic fumes of Br-. See also BROMIDES.

잠재적 노출

Used for making pharmaceuticals; as a warning gas in poisonous, odorless gasses; as a tear gas

운송 방법

UN1603 Ethyl bromoacetate, Hazard class: 6.1; Labels: 6.1-Poisonous materials.

Purification Methods

Wash the ester with saturated aqueous Na2CO3 (three times), 50% aqueous CaCl2 (three times) and saturated aqueous NaCl (twice). Dry with MgSO4, CaCl2 or CaCO3, and distil it. [Beilstein 2 IV 527.] LACHRYMATORY.

비 호환성

Vapor 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, and reducing agents. Esters are generally incompatible with nitrates. Moisture may cause hydrolysis or other forms of decomposition.
