and ethanol in the presence of concentrated sulfuric acid or
hydrochloric acid ester followed by distillation .
製造方法
By esterification of isovaleric acid with ethyl alcohol in the presence of concentrated H2SO4.
一般的な説明
A colorless oily liquid with a strong odor similar to apples. Less dense than water. Vapors heavier than air. Flash point 77°F. May mildly irritate skin and eyes.
空気と水の反応
Highly flammable. Slightly soluble in water.
反応プロフィール
ETHYL ISOVALERATE 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.
健康ハザード
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
