一般的な説明
A colorless liquid with a mild sweet odor. Flash point 113°F. A moderate fire risk. Inhalation may cause adverse effects. Insoluble in water and very soluble in alcohols and ethers. When heated to high temperatures emits acrid smoke and fumes. Used as a solvent and as a propellant in aerosols.
空気と水の反応
Highly flammable. Insoluble in water.
反応プロフィール
Hexyl acetate 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.
危険性
Combustible.
健康ハザード
May be harmful by inhalation, ingestion, or skin absorption. May cause irritation.
火災危険
Special Hazards of Combustion Products: Vapor may travel considerable distance to a source of ignition and flash back. Container explosion may occur under fire conditions. Forms explosive mixtures in air.
