Ethyl acetate (EtOAc) is a common solvent for extractions and purifications. EtOAc is a common solvent for certain reactions such as catalytic reductions involving palladium on carbon (Pd/C). However, EtOAc does not see widespread use as a solvent for reactions due to its tendency to hydrolyze under acidic or basic conditions.




Common Uses:


Solvent for reactions





Solvent for silica gel chromatography



Procedure excerpt:

…The resulting material was purified by silica gel column chromatography (10% EtOAc/hexane) to provide the product…




Solvent for extractions



Procedure excerpt:

…The mixture was concentrated in vacuo, diluted with H2O (200 mL), and extracted with EtOAc (2 x 200 mL). The combined organics…




Solvent for trituration



Procedure excerpt:

…The solid was slurried in EtOAc (350 mL) for 45 min at 15 C. The mixture was filtered, rinsing with 15 C EtOAc (2 x 250 mL), and dried…




Safety:


Ethyl acetate (EtOAc) is a very flammable liquid. EtOAc has a relatively low toxicity.
