Chemische Eigenschaften

Ethyl 2-Methylbutyrate is a liquid with a green, fruity odor reminiscent of apples. It is found, for example, in citrus fruits and wild berries and is used in fruit flavor compositions.

Occurrence

Reported found in nature; the ethyl l-methylbutyrate has been identified in strawberry juice; because of the presence of the asymmetric carbon, the compound should exhibit optically active forms as well as the racemic form; however, only the d-form and the racemic form are known. Reported found in apple juice, orange and grapefruit juice, bilberry, pineapple, strawberry, cheeses, milk, cognac, rum, whiskey, cider, mango, mountain papaya, spineless monkey orange (Strychnos madagasc.), Chinese quince and German chamomile oil.

synthetische

The racemic form can be prepared catalytically by several methods: from butene and Ni(CO)4 under nitrogen in ethyl alcohol/acetic acid solution, or from ethylene and CO under pressure using HBF4 and HF as catalysts.

Allgemeine Beschreibung

A colorless oily liquid with a fruity odor. Insoluble in water and less dense than water. Flash point 73°F. Contact may irritate skin, eyes and mucous membranes.

Air & Water Reaktionen

Highly flammable. Insoluble in water.

Reaktivit?t anzeigen

ETHYL-2-METHYL BUTYRATE 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

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.

Sicherheitsprofil

Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes.

Solubility in organics

Very slightly soluble in water, soluble in alcohol and Propylene glycol, miscible with perfume and flavor oils.
