Ethyl acetate is the ester of ethanol and acetic acid ; it is manufactured on a large scale for use as a solvent. The reaction can be accelerated by acid catalysis and aceato equilibrium can be shifted to the right by removal of water. 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.

Ether -like, fruity [1].

Acetic acidEthanol. A specialized industrial route entails the catalytic dehydrogenation of ethanol. Ethyl acetate is used primarily as a solvent and msdzbeing favored because of its low cost, low toxicity, and agreeable odor. Traces of rare-earth and 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.

Ethyl acetate

Lethal dose or concentration LDLC:. The rate constant is 0. Coffee beans and tea leaves are decaffeinated with this solvent.

Ethyl acetate is the most common ester in winebeing the product of the most common volatile organic acid — acetic acidand the ethyl alcohol generated during the fermentation.

These azeotropes are broken by pressure swing distillation or membrane distillation. Views Read Edit View history. This reaction gives ethanol and sodium acetatewhich is acetzto toward ethanol:.

Ethyl acetate – Wikipedia

LC 50 median concentration. LD 50 median dose. In a killing jar charged with ethyl acetate, the vapors will kill the collected insect quickly without destroying it. Exposure to oxygen can exacerbate the fault due to the oxidation of ethanol to acetaldehydewhich leaves the wine with a sharp vinegar -like taste.

Severe overexposure may cause weakness, drowsiness, and unconsciousness. The irritant effect of ethyl acetate is weaker than that of propyl acetate or butyl acetate.

Propyl etllo Propyl propanoate Isopropyl acetate Isopropyl palmitate. In the laboratory, and usually for illustrative purposes only, ethyl esters are typically hydrolyzed in a two-step process starting with a stoichiometric amount of a strong base, such as sodium hydroxide.

From Wikipedia, the free encyclopedia. R11R36R66R Overexposure to ethyl acetate may cause irritation of the eyes, nose, and throat. This method is stilo cost effective than the esterification but is applied with surplus ethanol in a chemical plant.

The combined annual production in of Japan, North America, and Europe was abouttonnes. In other projects Wikimedia Commons. Methyl acetatePropyl acetateButyl acetate. In the laboratory, mixtures containing ethyl acetate are commonly used in column chromatography and extractions.

Refractive index n D. Because it is not adetatoethyl acetate also keeps the insect soft enough to allow proper mounting suitable for a collection. 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.
