ABSTRACT:
A method of separating proximate boiling-point hydrocarbons using solutions of monovalent copper salts in solvents, said solvents being alkyl-substituted amides and alkyl esters of phosphorus-containing acids having a P.dbd.O group, N-alkyl-substituted amides of carboxylic acids, N-alkyl-substituted lactams, dialkyl sulphoxides, alkoxynitriles and N-alkyl-substituted aminonitriles. The method can be used for separating hydrocarbons from small quantities of acetylene compounds and cyclopentadiene.
Large quantities of acetylene compounds are separated from the mixture of proximate boiling-point hydrocarbons by contacting the mixture with said solvents containing no salts of monovalent copper.
