Esters ethyl acetate

NMR Chemical shift differences m their H NMR spectra aid the structure deter mmation of esters Consider the two isomeric esters ethyl acetate and methyl propanoate As Figure 20 9 shows the number of signals and their multiplicities are the same for both esters Both have a methyl singlet and a triplet-quartet pattern for their ethyl group...

It will now be convenient to pass on to that very important group of compounds, the esters. An ester is a combination of an alcohol with an acid, the combination being associated with the elimination of water. For example, ordinary ethyl alcohol combines with acetic acid to form the ester, ethyl acetate, according to the following equation —... [Pg.161]

From empirical observation, ILs tend to be immiscible with non-polar solvents. They can therefore be washed or brought into contact with diethyl ether or hexane to extract non-polar reaction products. Among solvents of greater polarity, esters (ethyl acetate, for example) exhibit variable solubility with ILs, depending on the nature of the IL. Polar or dipolar solvents (including chloroform, acetonitrile, and methanol) appear to be totally miscible with all ILs (excepting tetrachloroaluminate IL and the like, which react). Among notable exceptions, [EMIMJCl and [BMIMJCl are insoluble in dry acetone. [Pg.77]

The initial study of the La3 +-catalyzed methanolysis of carboxylate esters163 reported the apparent second-order rate constant for La2 + ( OCH3)2-catalyzed methanolysis of some representative examples of aryl esters (2, 5 and 2,4-dinitrophenyl acetate (14)), phenyl benzoate (15) and three aliphatic esters, ethyl acetate, isopropyl acetate (16) and tert-butyl acetate (17). Given in Table 6 are the rate constants for the La3+ and methoxide-catalyzed methanolysis of these esters along with... [Pg.288]

P.Y.173, an isoindolinone pigment, affords somewhat dull, greenish yellow shades. It shows average fastness to organic solvents, especially to alcohols (ethanol), esters (ethyl acetate), and ketones (including methylethylketone and cyclohexanone). Its solvent resistance equals step 3 on the 5 step scale. P.Y.173 is almost completely to completely fast to mineral spirits and xylene. [Pg.415]

Cured polymers obtained in this way show very high resistance to such solvents as petrol, water and ethanol. On the other hand they swell and absorb ketones, esters (ethyl acetate) and carbon tetrachloride. [Pg.371]

Polymers can also be synthesized from saturated monomers, e.g. by condensation of an organic acid with an alcohol into an ester with the formation of water. Simple alcoholes and fatty acids, such as ethyl alcohol (C2H5OH) and acetic acid (C2H5COOH) result in a low-molecular ester, ethyl acetate, but when bifunctional... [Pg.12]

Solubility in the solvent selected for application Currently the organic solvent are replaced with water as a suspension system, although certain types of film coatings may require organic solvents to be used. Commonly used solvents include alcohols (methanol, ethanol, and isopropanol), esters (ethyl acetate and ethyl lactate), ketones (acetone), and chlorinated hydrocarbons (dichlo-romethane and trichloroethane).

Esters, not fusel alcohols, actually comprise the most abundant group of volatile compounds in wines Rapp (26) has listed over 300 esters and lactones found in grapes, musts and wines. The esters are largely responsible for the fmity aromas associated with wine (52), especially young wine (27). Of the esters, ethyl acetate predominates by some two orders of magnitude (see 40) however, the low aroma thresholds of a number of the fatty acid ethyl esters makes them of sensory import nonetheless (27).
