Abstract: A PROCESS FOR RECOVERING ORGANIC LIQUIDS USED IN SOLVENT DYEING OPERATIONS OF TEXTILES IS DESCRIBED. THE ORGANIC LIQUID SOLVENTS COMPRISE A WATER-SOLUBLE COMPONENT AND A WATER INSOLUBLE COMPONENT WHICH, AS RESIDUAL LIQUORS FROM THE SOLVENT DYEING OPERATION CONTAIN A SMALL AMOUNT OF WATER ACCUMULATED DURING THE DYE OPERATION FROM THE TEXTILE BEING DYED AND FORM AN AZEOTROPIC MIXTURE WHEN RECOVERD BY DISTILLATION. THE MIXTURE IS RECOVERED AS IS COMPONENTS BY ADDITION OF WATER TO SEPARATE THE WATER INSOLUBLE COMPONENTS, FOLLOWED BY DISTILLATION. THE WATER AND THE WATER-SOLUBLE COMPONENT ALSO FORM AS AZEOTROPE FROM WHICH THE SOLUBLE ORGANIC COMPONENT IS RECOVERED BY THE ADDITION OF AN ENTRAINER FOLLOWED BY DISTILLATION. BOTH ORGANIC COMPONENTS MAY THEN BE RECYCLED TO THE SOLVENT DYEING PROCESS.

Abstract: RESIDUAL MOISTURE AND SULFUR AND OTHER RESIDUAL REDUCING AGENT IMPURITIES CONTAINED IN DRYCLEANING SOLVENTS ARE REMOVED BY ADDING TO THE SOLVENTS AN UNSUBSTITUTED AROMATIC HYDROCARBON OR A HALOGEN OR ALKYL SUBSTITUTED AROMATIC HYDROCARBON AND DRIED CELLULOSIC MATERIAL ON WHICH HAS BEEN PRECIPITATED A FINE DEPOSIT OF LEAD DICHROMATE. THE SAME MATERIALS MAY ALSO BE ADDED TO PETROLEUM PRODUCTS IN ORDER TO REMOVE SULFUR IMPURITIES THEREFROM.
