Abstract
Olefin complexing reagents comprising Cu(I) carboxylate/BF, adducts in aromatic solvents and a method of preparation therefor, and use of said reagents in the separation of olefins from paraffins are provided.
Claims9
A process for separating an olefin from a mixture of an olefin and a paraffin comprising the steps of:
- a) contacting said mixture of said olefin and said paraffin in an inert atmosphere with a complexing reagent consisting essentially of a copper(I) carboxylate/BF.sub.3 adduct in an aromatic solvent, whereby said olefin reacts with said complexing reagent to form an olefin/reagent complex in said aromatic solvent while said paraffin remains uncomplexed, wherein the molar ratio of said carboxylate to said BF.sub.3 in said reagent is about 1:2;
- b) separating said olefin/reagent complex from said uncomplexed paraffin;
- and
- c) recovering said olefin from said olefin/reagent complex.
