In acetone vapor at ambient temperature, only 2.4 × 10 −7 % of the molecules are in the enol form. [ 46 ] In the presence of suitable catalysts , two acetone molecules also combine to form the compound diacetone alcohol (CH 3 )C=O(CH 2 )C(OH)(CH 3 ) 2 , which on dehydration gives mesityl oxide (CH 3 )C=O(CH)=C(CH 3 ) 2 .
Acetone and acetic anhydride ((CH 3 C(O)) 2 O) upon the addition of boron trifluoride (BF 3) catalyst: [11] (CH 3 C(O)) 2 O + CH 3 C(O)CH 3 → CH 3 C(O)CH 2 C(O)CH 3 A second synthesis involves the base-catalyzed condensation (e.g., by sodium ethoxide CH 3 CH 2 O − Na + ) of acetone and ethyl acetate , followed by acidification of the sodium ...
