Ethyl isobutyrate Usage And Synthesis

Chemical Properties	Colorless volatile liquid. With aromas of fruit and cream. Melting point is -88 DEG C, and boiling point is 112 ~ 113 C. Slightly soluble in water and miscible with most organic solvents. The natural product is found in strawberries, honey, molasses, beer and champagne.
Uses	Used as food essence and flavoring, mainly used in the preparation of cream and strawberry, cherry and other fruit essences. It can also be used as raw flavoring in cigarettes, daily chemical products and other products. At the same time, it is also an excellent organic solvent.
Use restriction	FEMA(mg/kg)：Soft drink 10; cold drink 25；sweets 73; baked food 200; puddings6.0; piping layers 1.5.
Preparation	Obtained by esterification of isobutyric acid and anhydrous ethanol. After mixing isobutyric acid and anhydrous ethanol, carefully add concentrated sulfuric acid. After refluxing the mixture for 14h, it should be washed by water and saturated sodium bicarbonate solution and dried by anhydrous magnesium sulfate and then go through distillation. Collecting fractions at 109-111℃ and obtain 2- methyl ethyl propionate. The yield is 69 percent.
Toxicity	GRAS (FEMA) LD50800mg/kg (mice, subcutaneous )
Content Analysis	Adopt method one offered by the ester measurement. The sample is taken 1.0 gram by weight. Equivalent factor under calculation is taken at 58.08. It should be measured with non-polar column method used in GT-10-4.
Chemical Properties	Ethyl isobutyrate has a fruity aromatic odor.
Chemical Properties	CLEAR COLOURLESS LIQUID
Uses	Ethyl Isobutyrate is a synthetic flavoring agent that is a stable, col- orless liquid of dry, fruity odor. it should be stored in tin, glass, or resin-lined containers. it is used to give fruity effects to flavors for applications in candy, baked goods, and beverages at 10–100 ppm.
Uses	manufacture of flavoring Compounds and essences.
Definition	ChEBI: A fatty acid methyl ester obtained by the formal condensation of isobutyric acid with ethanol.
Preparation	By esterification of ethanol with isobutyric acid under azeotropic conditions.
Aroma threshold values	Detection: 0.01 to 1 ppb
Taste threshold values	Taste characteristics at 12.5 ppm: pungent, ethereal and fruity with a rum- and eggnog-like nuance. Taste characteristics at 20 ppm: sweet, ethereal, fruity with a rum-like nuance
General Description	A colorless volatile liquid with a fruity, aromatic odor. Less dense than water and insoluble in water. Flash point below 60°F. Vapors heavier than air. May irritate skin and eyes. Used to make flavoring extracts and other chemicals.
Air & Water Reactions	Highly flammable. Insoluble in water.
Reactivity Profile	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.
Safety Profile	Moderately toxic by intraperitoneal route. A skin irritant. Flammable liquid. A very dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS.
Purification Methods	Wash the ester with aqueous 5% Na2CO3, then with saturated aqueous CaCl2. Dry it over CaSO4 and distil. [Beilstein 1 IV 846.]
