  • Separating unequally saturated hydrocarbons with monovalent copper salt solutions in .beta.-methoxypropionitrile
    Patent number: 4141925
    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.
