Abstract:
The present invention describes a process for the production of octenes from ethylene by dimerizing ethylene to butenes and by dimerizing butenes to octenes.
Abstract:
Catalytic composition comprising at least one non-aqueous ionic liquid medium of general formula Q1+A1−, in which Q1+ represents an organic cation and A1− represents an anion, and at least one ionic component of general formula Q2+A2−, in which Q2+ represents an organic cation comprising at least one sulphonic acid or carboxylic acid function, and A2− represents an anion. The invention also relates to an isobutene dimerization process using the catalytic composition.
Abstract:
Catalytic composition comprising at least one Brønsted acid, designated HB, dissolved in a non-aqueous liquid medium of general formula Q1+A1−, in which Q1+ represents an organic cation and A1− represents an anion, said composition also comprising an additive Q2+A2− in which Q2+ represents an organic cation containing at least one alcohol function and A2− represents an anion. The invention also relates to an isobutene dimerization process using the catalytic composition.
