Description

General description

Ethyl acetate is an effective alternate solvent of diethyl ether.[1]

Application

Ethyl acetate has been used as solvent for the isolation of Rose hip (Rosa canina L., Rosaceae) powder, via sonication.[2] 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).[3]
