Beschreibung
Isobutyl formate has a fruity, ether-like odor and a sweet taste reminiscent of rum. Isobutyl formate may be prepared from isobutyl alcohol and carbon monoxide in the presence of sodium isobutylate at 110°C and 400 atm.
Chemische Eigenschaften
Isobutyl formate has a fruity, ether-like odor and a sweet taste reminiscent of rum.
Chemische Eigenschaften
CLEAR COLOURLESS TO LIGHT YELLOW LIQUID
Occurrence
Reported found in pineapple, apple, vinegar, wheat bread, beer, cognac and rum.
Verwenden
Isobutyl Formate is a synthetic flavoring agent that is a stable, colorless liquid of fruity odor. storage should be in glass or tin containers. it is used in fruit flavors such as pear, raspberry, and other berry flavors with applications in beverages, ice cream, candy, and baked goods at 2–18 ppm.
Definition
ChEBI: 2-Methylpropyl formate is a carboxylic ester.
synthetische
From isobutyl alcohol and carbon monoxide in the presence of sodium isobutylate at 110°C and 400 atm
Taste threshold values
Taste characteristics at 10 ppm: slightly sweet, fresh, gives lift, fruity
Allgemeine Beschreibung
A colorless liquid. Less dense than water. Flash point 60°F. Vapors heavier than air. Vapors may be narcotic and irritating in high concentrations. Used as a solvent and to make perfumes.
Air & Water Reaktionen
Highly flammable. Soluble in water.
Reaktivität anzeigen
Isobutyl formate 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.
Brandgefahr
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.
Biochem/physiol Actions
Taste at 10 ppm
Synthese
Iso-BUTYL FORMATE is synthesized from iso-Butanol by direct esterification with formic acid under azeotropic conditions, using e. g. para-Tolylsulfonic acid catalyst.
läuterung methode
Wash the formate with saturated aqueous NaHCO3, in the presence of saturated NaCl solution until no further reaction occurs, then with saturated aqueous NaCl, dry (MgSO4) and fractionally distil it. [Beilstein 2 H 21, 2 I 18, 2 II 30, 2 III 41, 2 IV 29.]
