Ethyl acetate ethanoate

To obtain an accurate quantitative analysis of the composition of a mixture, a knowledge of the response of the detector to each component is required. If the detector response is not the same for each component, then the areas under the peaks clearly cannot be used as a direct measure of the proportion of the components in the mixture. The experiment described illustrates the use of an internal normalisation method for the quantitative analysis of a mixture of the following three components ethyl acetate (ethanoate), octane, and ethyl n-propyl ketone (hexan-3-one).

Of this product, 4.5 g in 30 cc of dry isopropyl alcohol are refluxed for 16 hours with 2.5 g of (3-chloroethyl dimethyl amine. The solution is cooled and filtered clear from the solid by-product. The solvent is removed under reduced pressure on the steam bath and the residue is washed with anhydrous ether. It is dissolved in ethyl acetate from which it crystallizes. It is the hydrochloride of (3-(dimethylamino)ethyl ester of 2-phenyl-2-( 1-hy-droxycyclopentyl) ethanoic acid, melting at 134° to 136°C. 

An example of a reversible reaction in the liquid phase is afforded by the esterification reaction between ethanol and acetic (ethanoic) acid forming ethyl acetate and water. Since, however, ethyl acetate undergoes conversion to acetic acid and ethanol when heated with water, the esterification reaction never proceeds to completion. 

Discussion. Hydroxyl groups present in carbohydrates can be readily acetylated by acetic (ethanoic) anhydride in ethyl acetate containing some perchloric acid. This reaction can be used as a basis for determining the number of hydroxyl groups in the carbohydrate molecule by carrying out the reaction with excess acetic anhydride followed by titration of the excess using sodium hydroxide in methyl cellosolve. 

Whilst some organic compounds can be investigated in aqueous solution, it is frequently necessary to add an organic solvent to improve the solubility suitable water-miscible solvents include ethanol, methanol, ethane-1,2-diol, dioxan, acetonitrile and acetic (ethanoic) acid. In some cases a purely organic solvent must be used and anhydrous materials such as acetic acid, formamide and diethylamine have been employed suitable supporting electrolytes in these solvents include lithium perchlorate and tetra-alkylammonium salts R4NX (R = ethyl or butyl X = iodide or perchlorate). 

Ethyl acetate is an ester that can be synthesized by reacting ethanoic acid (acetic acid) with ethanol. At room temperature, the equilibrium constant for this reaction is 2.2.

You will need to be able to reorientate stmctures without making mistakes, and also to be able to recognize different versions of the same thing. A simple example is with esters, where students have learnt that ethyl acetate (ethyl ethanoate) can be abbreviated to CH3CO2C2H5. When written backwards, i.e. C2H5OCOCH3, the ester functionality often seems less recognizable.

You can use diisobutylaluminum hydride to reduce both esters and nitriles to aldehydes. Typical examples are the reduction of ethyl ethanoate (ethyl acetate) and ethanenitrile (acetonitrile) to ethanal (acetaldehyde). 

Some esters have characteristic fruity smells and are generally used as excellent industrial solvents. Esters like ethyl ethanoate, also called ethyl acetate, are used as a solvents for glues. It is this compound that glue sniffers love. Unfortunately they do not realize that it kills off brain cells and can eventually lead to death.

For liquid-liquid extraction, water is usually the polar solvent. Since most extractions involve getting the required compound into the organic solvent (or removing unwanted ionic chemicals from it), it should have good solvent power for the desired compound and a low boiling point for ease of removal and recovery of the compound. The common organic solvents used in liquid-liquid extraction are diethyl ether (ethoxyethane) b.pt. 34 °C, dichloromethane (DCM) b.pt. 41 °C and ethyl acetate (ethyl ethanoate) b.pt. 77 °C. Dichloromethane is denser than water and forms the lower layer, whereas diethyl ether and ethyl acetate float on water and are the upper layer.

Names of Esters.—Considering these compounds as ethereal salts they are named on the same principal as metal salts, the name of the alkyl radical being used in place of that of the metal. The ester of ethyl alcohol and acetic add, CH3COOC2H5, being called ethyl acetate or ethyl ethanoate. Considering them as esters they are named as follows ethyl acetate is acetic acid ethyl ester or ethanoic acid ethane ester.
