Abstract
1420446 Separating olefins from mixtures EXXON RESEARCH & ENG CO 31 May 1973 [2 June 1972] 26024/73 Heading C5E In a process for the separation and recovery of complexible olefins by contacting a feedstream with an aromatic sorbent solution containing a cuprous salt whose anionic component is a Lewis acid, alkylation and polymerization side reactions are reduced by incorporating an organic phosphine and an organic nitrogen base in the sorbent solution. The phosphine suitably has the formula R 1 R 2 R 3 P wherein R 1 , R 2 and R 3 are C 1-20 alkyl radicals, phenyl radicals, C 7-12 alkylaryl or aralkyl radicals. The nitrogen base can be an alkyl substituted pyridine, a tertiary alkyl amine or a tertiaryalkylarylamine. Suitable cuprous salts are CuPF 6 , CuBF 4 , CuBF 3 Cl, CuAlCl 4 , CuAlBr 4 , CuTaF 6 and CuAlClxBy (wherein x and y are integers whose -sum is 4). The sorbent solution can contain benzene, cumene or methyl biphenyl as the solvent. In the separation and recovery of ethylene or propylene the-feed can be contacted with the sorbent solution at 20-300 C. and 0À5-50 atm. abs.
