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
Procedure excerpt:
To a solution of the SM (10.9 g, 27.7 mmol) in EtOAc (100 mL) was added SnCl2-2H2O (18.7 g, 83.1 mmol). The reaction mixture was stirred at 50 C overnight. The mixture was . . .
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.
