메틸 아세토아세테이트 C화학적 특성, 용도, 생산
화학적 성질
Colorless, clear liquid용도
Methyl acetoacetate (MAA) is a starting material for the syntheses of alpha-substituted aceto- acetic esters and cyclic compounds, e.g. pyrazole, pyrimidine and coumarin derivatives.생산 방법
Methyl acetoacetate is produced by a reaction of methyl acetate with sodium methoxide.주요 응용
Methyl acetoacetate (MAA) has been used for the following applications:As a chemical reagent for organic synthesis and as a solvent for cellulose ethers;
As a chemical intermediate for organic compounds, used for the synthesis of nifedipine;
As a food additive, used as an amine protectant for synthetic sweeteners;
As a pharmaceutical raw material, used in the manufacture of antibiotics.
일반 설명
A clear colorless liquid. Flash point 158°F. Denser than water and slightly soluble in water. Vapors heavier than air.공기와 물의 반응
Very slightly soluble in water.반응 프로필
Methyl acetoacetate 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 hydrides위험도
Toxic by ingestion and inhalation.건강위험
May be harmful by inhalation, ingestion, or skin absorption. Causes eye irritation. May cause skin irritation.Safety Profile
Moderately toxic by ingestion. A skin and severe eye irritant. Combustible when exposed to heat or flame. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS.Carcinogenicity
