strawberry, melon, peas, peppermint oil, pepper, blue, Gruyere and parmesan cheese, coffee, honey, olive, mushroom, jackfruit,
cherimoya, sage, custard apple, nectarine, lamb’s lettuce and cape gooseberry
製造方法
By esterification of isovaleric acid with methyl alcohol at the boil in the presence of concentrated H2SO4.
一般的な説明
A colorless liquid. Flash point below 70°F. Less dense than water and insoluble in water. Vapors heavier than air. May be slightly toxic by ingestion and inhalation. Used to make other chemicals.
空気と水の反応
Highly flammable. Insoluble in water.
反応プロフィール
Methyl 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
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.
火災危険
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.
