WebAcetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O.Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis.It is a colorless liquid that smells strongly of acetic acid, which is formed by its reaction with moisture in the air. WebSep 4, 2012 · Non-polar carotenoids (e.g., lycopene and β-carotene) are more soluble in hexane and ethyl acetate [24,25] while more polar carotenoids (e.g., lutein or epoxy carotenoids) show greater solubility in EtOH and acetone [6,26]. Because acetone is widely used for carotenoid extraction , we assayed it as the first extraction solvent to replace THF.
