This reaction takes place by an E2 elimination mechanism and creates a C=C double bond conjugated with the carbonyl. In this process a butanebutylene stream from which butadiene and isobutylene have been removed reacts with acetic acid in the presence of acid ion- exchange resin at 100120C and 15002000 kPa (about 1520 atm) (see Acetic acid and its derivatives, acetic acid ). Protonation of the double bond gives another resonance-stabilized carbocation: This carbocation is also the conjugate acid of a ketone. Furthermore, IR analysis indicated that the Ti atoms in the catalyst act as a Lewis acid, which coordinates to the oxygen atoms of acetic acid, enhancing the attack of hydrogens activated on neighboring Ni-Sn alloys.
