| Methyl isovalerate Usage And Synthesis |
| Description | Methyl isovalerate has a strong, pungent, apple-like odor and a
bitter flavor. It may be prepared by esterification of isovaleric acid
with methyl alcohol at the boil in the presence of concentrated H2SON4. | | Chemical Properties | Methyl isovalerate has a strong, pungent, apple-like odor and a bitter flavor. This compound is also reported to have an
herbaceous, fruity odor. | | Chemical Properties | clear slightly yellow liquid | | Occurrence | Reported found in the juice of a few varieties of Florida oranges, pineapple, apple, banana, bilberry, blueberry,
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 | | Preparation | By esterification of isovaleric acid with methyl alcohol at the boil in the presence of concentrated H2SO4. | | Aroma threshold values | Detection: 4.4 to 44 ppb | | Taste threshold values | Taste characteristics at 80 ppm: fruity, pineapple, apple with a juicy, fruit-like nuance | | Synthesis Reference(s) | Tetrahedron Letters, 8, p. 4805, 1967 DOI: 10.1016/S0040-4039(01)89607-6 | | General Description | 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. | | Air & Water Reactions | Highly flammable. Insoluble in water. | | Reactivity Profile | 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. | | Health Hazard | 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. | | Fire Hazard | 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. |
