PROCESS FOR SELECTIVE EXTRACTION OF TETRAHYDRO-FURANE FROM WATERY POLLUTIONS CONSISTING OF POLARIC COMPONENT/S

Selective extraction of THF from dilute aq. solns. also contg. one or more polar components, is effected by: (a) extracting the THF using a non-polar organic solvent (I); and (b) recovering the THF from the extract by known rectification methods, (I) being recycled if desired to step (a).

Summary:Selective extraction of THF from dilute aq. solns. also contg. one or more polar components, is effected by: (a) extracting the THF using a non-polar organic solvent (I); and (b) recovering the THF from the extract by known rectification methods, (I) being recycled if desired to step (a). ADVANTAGE - The process is economical and efficient.
