It is made of liquid ethylene, chloromethane or hexane polymerized at low temperature with aluminum chloride as catalyst. At the end of polymerization, the temperature of the reaction mixture was raised to remove the volatile components. Isobutene is obtained from naphtha cracking and then catalyzed by polymerization.


The C4 fraction was first converted into the corresponding diol tertiary butyl ether intermediate with the suitable diol ether, and then decomposed at high temperature to obtain pure isobutene and recover the diol. The advantage of this process is that the catalyst is solid, no solvent is used, and there is no equilibrium restriction due to catalytic selectivity.
