Isoamyl Acetate

Isoamyl acetate is an organic compound that is the ester formed from isoamyl alcohol and acetic acid. It has a strong odor similar to Juicy Fruit or a pear drop which is also described as similar to both banana and pear. Banana oil is a term that is applied either to pure isoamyl acetate or to flavorings that are mixtures of isoamyl acetate, amyl acetate, and other flavors. It is used to confer banana flavor in foods. Pear oil commonly refers to a solution of isoamyl acetate in ethanol that is used as an artificial flavor. It is also used as a solvent for some varnishes and nitrocellulose lacquers, as well as being a honey bee pheromone and can be used to attract large groups of honeybees to a small area. As a solvent and carrier for materials such as nitrocellulose, it was extensively used in the aircraft industry for stiffening and wind-proofing fabric flying surfaces, where it and its derivatives were generally known as dope. Because of its intense, pleasant odor and its low toxicity, isoamyl acetate is used to test the effectiveness of respirators or gas masks.

Isobutanol is an organic compound. Its isomers include n-butanol, 2-butanol, and tert-butanol. Isobutanol is produced by the carbonylation of propylene. Isobutanol is also produced naturally during the fermentation of carbohydrates and may also be a byproduct of the decay process of organic matter. Isobutanol, along with other low molecular weight alcohols can also be produced by some engineered microorganisms such as corynebacterium. It is useful in organic synthesis, as a chemical intermediate and as a solvent in coating applications. Isobutanol is similar in property to n-butyl alcohol and may be used as a supplement or replacement for n-butyl alcohol in many applications. Isobutanol could possibly serve as an alternative to gasoline to fuel combustion engines.

Isobutyl Acetate

Isobutyl acetate is used as a solvent for lacquer and nitrocellulose.It occurs naturally in raspberries, pears and other plants. At higher concentrations the odor can be unpleasant and may cause symptoms of central nervous system depression such as nausea, dizziness and headache.
