Concentrated cuprous nitrate/propionitrile solutions as complexing agents for olefin separations
Abstract
Abstract ANHYDROUS CUPROUS NITRATE/PROPIONITRILE SOLUTIONS HAVING HIGH CONCENTRATIONS OF CUPROUS ION, E.G., 15-26% BY WEIGHT CUPROUS ION, AND CORRESPONDINGLY LOW CONCENTRATIONS OF CUPRIC ION, E.G., 2-5% BY WEIGHT CUPRIC ION, AND THE PREPARATION THEREOF BY (1) CONTACTING QUANTITIES OF CUPRIC NITRATE AND METALLIC COPPER SUFFICIENT TO YIELD NO MORE THAN ABOUT 4% CUPROUS ION IN PROPIONITRILE SOLVENT AT ELEVATED TEMPERATURES TO PRODUCE A DILUTE PROPIONITRILE SOLVEN SOLUTION WHEREIN THE COPPER IS PRESENT SUBSTANTIALLY IN THE CUPROUS FORM AND (2) CONCENTRATING THE DILUTE/PROPIONITRILE SOLUTION. THE CONCENTRATED CUPROUS NITRATE/PROPIONITRILE SOLUTIONS, THUSLY PREPARED, ARE USEFUL IN AFFECTING THE SEPARATION OF OLEFINICALLY UNSATURATED HYDROCARBONS FROM HYDROCARBONS OF LESSER DEGREES OF UNSATURATION.
