에틸 크로톤산 화학적 특성, 용도, 생산

화학적 성질
Ethyl crotonate has a powerful, sour, caramellic-fruity odor.
출처
Reported found in Fragaria vesca. Also reported found in guava fruit, guava peel, pineapple, white wine, yellow passion fruit, fresh mango, naranjilla fruit, mussel, loganberry, apple, papaya, concord grape, strawberry, rum, cocoa, plum, kiwifruit and other natural sources.
용도
Crotonic Acid Ethyl Ester, is an intermediate for the preparation of various pharmaceutical compounds. It can be used for the synthesis of (+)-trans-Trikentrin A.
제조 방법
By esterification of crotonic acid with ethyl alcohol in the presence of concentrated H2SO4.
일반 설명
A clear colorless liquid with a pungent odor. Flash point 36°F. Less dense than water and insoluble in water. Vapors heavier than air.
공기와 물의 반응
Highly flammable. Insoluble in water.
반응 프로필
ETHYL CROTONATE is an 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.
건강위험
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
화재위험
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Safety Profile
Slightly toxic by ingestion. Corrosive. An eye irritant and lachrymator. A flammable liquid. When heated to decomposition it emits acrid smoke and irritating fumes.
