3-Methyl-2-pentanone -LRB- methyl sec-butyl ketone -RRB- is an aliphatic ketone and isomer of 2-hexanone .. ketone. ketone. 2-hexanone. 2-hexanone. It is used as a solvent and as an intermediate for syntheses .. Its industrial importance is low .. It is produced by base-catalyzed aldol condensation of 2-butanone with acetaldehyde , forming 4-hydroxy-3-methyl-2-pentanone , which is dehydrated to 3-methyl-3-penten-2-one over an acid catalyst , followed by hydrogenation over a palladium catalyst .. aldol condensation. aldol condensation. 2-butanone. 2-butanone. acetaldehyde. acetaldehyde. 4-hydroxy-3-methyl-2-pentanone. 4-hydroxy-3-methyl-2-pentanone. dehydrated.
