Ethyl acetate ethanol to acetaldehyde, which leaves the wine with a sharp vinegar-like taste. In the field of entomology, ethyl acetate is an effective asphyxiant for use in insect collecting and study. In a killing jar charged with ethyl acetate, the vapors will kill the collected insect quickly without destroying it. Because it is not hygroscopic, ethyl acetate also keeps the insect soft enough to allow proper mounting suitable for a collection. Ethyl acetate can be hydrolyzed in acidic or basic conditions to regain acetic acid and ethanol. The use of an acid catalyst accelerates the hydrolysis, which is subject to the
Ethyl iodide excellent ethylating agent. It is also used as the hydrogen radical promoter. Ethyl iodide is prepared by using red phosphorus, absolute ethanol and iodine ; the phosphorus and iodine dissolve in the ethanol, where they form phosphorus triiodide, which must be formed "in situ" because it is unstable. During the process the temperature is controlled. The crude product is purified by distillation. Ethyl iodide Ethyl iodide (also iodoethane) is a colorless, flammable chemical compound. It has the chemical formula CHI and is prepared by heating ethanol with iodine and phosphorus. On contact with air, especially on the effect of light,
