General description

Ethyl acetate is an effective alternate solvent of diethyl ether, employed for the concentration of eggs, larvae, and cysts in fecal specimens during the Formalin-ether sedimentation technique. Acetaldehyde is reaction intermediate formed during the oxidative combustion of ethanol and ethyl acetate in the presence of copper oxide embedded on Ce-doped titania surface.

Application

Ethyl acetate may be used as solvent for the synthesis of γ-benzyl-L-glutamic acid N-carboxy anhydride (BLG-NCA).
