| Description | Isobutyl isobutyrate has an odor and taste reminiscent of pineapple. May be synthesized by catalytic reaction passing vapors of isobutyl alcohol over CuO + Al2O3, ZnO + Al2O3, or CuO + ZnO + Al2O3 at 350 - 400°C under pressure. |
| Chemical Properties | Isobutyl isobutyrate has an odor and taste reminiscent of pineapple. |
| Chemical Properties | CLEAR LIQUID |
| Occurrence | Reported found in the essential oil of hops, grapes, apricot, banana, melon, strawberry, cider, passion fruit wine, sherry, grape wines, whiskey, olive, quince, plum wine, laurel, myrtle leaf and berry, Chinese quince and Roman chamomile oil. |
| Uses | Isobutyl isobutyrate is used principally as a solvent, especially for nitrocellulose lacquers and thinners as well as coatings for plastic substrates, and high-solids coatings. The majority of end uses are in coatings (automotive, industrial, wood furniture, and graphic arts). |
| Uses | Flavoring, insect repellent, nitrocellulose lacquers and thinners, substitute for methyl amyl acetate. |
| Definition | ChEBI: 2-Methylpropyl 2-methylpropionate is a carboxylic ester. |
| Preparation | By catalytic reaction passing vapors of isobutyl alcohol over CuO + Al2O3, ZnO + Al2O3, or CuO + ZnO + Al2O3 at 350 to 400°C under pressure |
| Aroma threshold values | Detection: 36 ppb to 4.37 ppm; aroma characteristics at 1.0%: sweet, estry and fruity, winey, plum, apple and banana-like |
| General Description | A colorless liquid with a pleasant fruity odor. Moderately toxic by inhalation. Insoluble in water and floats on water, but soluble in alcohol and ethers. Isobutyl isobutyrate is used as a flavoring and in the manufacture of insecticides. |
| Air & Water Reactions | Highly flammable. Insoluble in water. |
| Reactivity Profile | Isobutyl isobutyrate, [FLAMMABLE LIQUID] reacts 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 with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides. |
| Hazard | Toxic by inhalation. |
| Health Hazard | Exposure can cause irritation of eyes, nose and throat. Toxic by inhalation. |
