Abstract
A process and apparatus for separating monoolefins from other monoolefins comprising contacting a mixture of different monoolefins with a complexing agent selected from the group consisting of copper (I) salts of sulfonic acids and copper (I) salts of dialkyl phosphates and a suitable hydrocarbon solvent for the complexing agent under such conditions that the monoolefins form different strength complexes with the complexing agent. The different strength of the complexes provides a mechanism by which even closely boiling monoolefin isomers may be separated.
Claims11
A process for at least partially separating a first monoolefin from admixture with a second monoolefin, wherein said first monoolefin forms a stronger complex than said second monoolefin with a complexing agent selected from the group consisting of copper (I) salts of sulfonic acids and copper (I) salts of dialkyl phosphates, said process comprising the steps of:
- contacting the mixture of said first monoolefin and said second monoolefin with said complexing agent and a suitable hydrocarbon solvent for said complexing agent under such conditions that said first monoolefin forms a stronger complex than said second monoolefin with said complexing agent;
- and
- separating said first monoolefin from said second monoolefin based on the relative strengths of the first monoolefin complex and the second monoolefin complex.
