General description

Ethyl acetate is an effective alternate solvent of diethyl ether.

Application

Ethyl acetate has been used as solvent for the isolation of Rose hip (Rosa canina L., Rosaceae) powder, via sonication. It has been used as solvent for the abstraction of volatile thiols from wine for their quantitative estimation by gas chromatography/mass spectrometry (GC-MS).

As volatile thiols are nucleophiles, they are capable of additional reactions with electrophiles. In enology, this concerns reactions between volatile or non-volatile thiols and oxidized phenolic compounds. Initial studies concerning the reactivity of volatile thiols with polyphenols showed that (+)-catechin
