Other names Acetic ester Acetic ether Ethyl ester of acetic acid. Excessive amounts of ethyl acetate are considered a wine fault.
From Wikipedia, the free encyclopedia.
Propyl acetate Propyl propanoate Isopropyl acetate Isopropyl palmitate. In a killing jar charged with ethyl acetate, the vapors will kill the collected insect quickly without destroying it. In the field of entomologyethyl acetate is an effective asphyxiant for use in insect collecting and study. LC Lo lowest published. Ethyl acetate is the most common ester in winebeing the product of the most common volatile organic acid etiloo acetic acidand the ethyl alcohol generated during the fermentation.
Ether -like, fruity .
This reaction gives ethanol and sodium acetatewhich is unreactive toward ethanol:. These azeotropes are broken by pressure swing distillation or membrane distillation. A specialized industrial route entails the catalytic dehydrogenation of ethanol. Because it is not hygroscopicethyl acetate also keeps the insect soft enough to allow proper mounting suitable for a collection.
This method is more cost effective than the esterification but is applied with surplus ethanol in a chemical plant.
Solubility in ethanolacetone eilo, diethyl etherbenzene. For example, it is commonly used to clean circuit boards and in some nail varnish removers acetone and acetonitrile are also used.
Exposure to oxygen can exacerbate the fault due to the oxidation of ethanol to acetaldehydewhich leaves the wine with a sharp vinegar -like taste. Methyl formate Methyl acetate Methyl propionate Methyl butyrate Methyl pentanoate.
Patty’s Industrial Hygiene and Toxicology. Ethyl acetate is synthesized in industry mainly via the classic Fischer esterification reaction of ethanol and acetic acid.
Ethyl acetate – Wikipedia
In other projects Wikimedia Commons. Traces of rare-earth etjlo alkali metals are beneficial to the process. The use of an acid catalyst accelerates the hydrolysis, which is subject to the Fischer equilibrium mentioned above.
The rate constant is 0. Acetic acidEthanol. Overexposure to ethyl acetate may cause irritation of the eyes, nose, and ehilo. The Oxford Companion to Wine 3rd ed. Ethyl acetate is used primarily as a solvent and diluentbeing favored because of its low cost, low toxicity, and agreeable odor. LC 50 median concentration. Ethyl acetate is rarely selected as a reaction solvent because it is prone to hydrolysis and transesterification.
In the laboratory, mixtures containing ethyl acetate are commonly used in column chromatography and extractions.
Refractive index n D. Acetic ester Acetic ether Ethyl ester of acetic acid. It is also prepared in industry using the Tishchenko reactionby combining two equivalents of acetaldehyde in the presence of an alkoxide catalyst:. Lethal dose or concentration LDLC:. Byproducts of the dehydrogenation include diethyl etherwhich is thought to arise primarily due to aluminum sites in the catalyst, acetaldehyde and its aldol products, higher esters, and ketones.
Separations of the byproducts are complicated by the fact that ethanol forms an azeotrope with water, as does ethyl acetate with ethanol and water, and methyl ethyl ketone MEK, which forms from 2-butanol with both ethanol and ethyl acetate. In perfumes, it evaporates quickly, leaving only the scent of the perfume on the skin.
