Abstract
Complexing reagents are provided which comprise Cu(I) carboxylates or Cu(I) sulfonates and high molecular weight olefins. The invention complexing reagents are useful for separating olefins from mixtures of olefins and paraffins.
Claims5
A process for separating a low molecular weight olefin from admixture with paraffins comprising the steps of
- a) contacting said admixture under an inert atmosphere with a complexing reagent solution comprising a copper (I) carboxylate and a high molecular weight olefin having about 10 to about 20 carbon atoms, whereby said low molecular weight olefin forms a substantially soluble olefin/reagent complex while said paraffins remain insoluble;
- b) separating said substantially soluble olefin/reagent complex from said insoluble paraffins;
- and
- c) recovering said low molecular weight olefin from said substantially soluble olefin/reagent complex.
