APPLICATION OF ALLOYED DERIVATIVES OF MELONAMIDE TO EXTRACTION BY FE (III) SOLVENTS OF CONCENTRATED CLORETHED SOLUTIONS

摘要

The application of alkylated derivatives of melonamide is to the extraction by solvents of Fe (III) of concentrated chlorinated solutions in industrial chemistry, such as N,N'-diphenyl-N,N' dimethyl melonamide, N,N'-diphenyl- N,N'-dimethyl tetradecyl- melonamide and N,N'-dibutyl- N,N'-dimethyl melonamide to the recovery and/or removal of Fe (III) from concentrated chlorinated solutions is shown to be highly advantageous in comparison with commonly used methods. Thus, after an efficient contact of a solution 0.1 M of the compounds in 1.2 dichloroethane with equal volumes of solutions of chloridic acid of 8 to 12 M containing approximately 0.01 M in Fe (III) during 15 minutes, the metallic ion is quantitatively extracted for the organic phase, being re-extracted totally from the organic medium by new contact with an equal volume of water.
