Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3 CO 2 CH 2 CH 3, simplified to C 4 H 8 O 2.This flammable, colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and the decaffeination process of tea and coffee.
At large scale, ethyl acetoacetate is industrially produced by treatment of diketene with ethanol. [2] The small scale preparation of ethyl acetoacetate is a classic laboratory procedure. [3] It involves Claisen condensation of ethyl acetate. Two moles of ethyl acetate condense to form one mole each of ethyl acetoacetate and ethanol. [4]
[4] [6] Alcohol dehydrogenase and aldehyde dehydrogenase are present at their highest concentrations (in liver mitochondria). [98] [107] But these enzymes are widely expressed throughout the body, such as in the stomach and small intestine. [2] Some alcohol undergoes a first pass of metabolism in these areas, before it ever enters the ...

This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
The classic synthesis is the Fischer esterification, which involves treating a carboxylic acid with an alcohol in the presence of a dehydrating agent: RCO 2 H + R'OH ⇌ RCO 2 R' + H 2 O. The equilibrium constant for such reactions is about 5 for typical esters, e.g., ethyl acetate. [15] The reaction is slow in the absence of a catalyst.
A specially denatured alcohol is a combination of ethanol and another chemical substance, e.g., ethyl acetate in SDA 29, 35, and 35A, added to render the mixture unsuitable for drinking. [12] SDAs are often used in cosmetic products, and can also be used in chemical manufacturing, pharmaceuticals, and solvents. [13]
