Axens Dimersol-X process transforms butenes to octenes that are ultimately used in the manufacture of plasticizers via isononanol (isononyl alcohol), and diisononyl phthalate units.
Thirty-five Dimersol units treating various olefinic C3 and C4 cuts have been licensed. Typical octenes production capacities range from 20,000 t/y up to 90,000 t/y.
