Определение
ChEBI: A fatty acid methyl ester resulting from the formal condensation of the carboxy group of octanoic acid with the hydroxy group of methanol.
Общее описание
A colorless liquid. Flash point 130°F. Insoluble in water and about the same density as water. Used to make other chemicals.
Реакции воздуха и воды
Insoluble in water.
Профиль реактивности
Caprylic acid methyl ester 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.
Угроза здоровью
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.
Методы очистки
Pass the ester through alumina and distil it before use. [Beilstein 2 IV 986.]
