Abstract: COMPOSITIONS COMPRISING A PERCHLOROFLUOROCARBON ARE STABILIZED AGAINST REACTION WITH LOWER MOLECULAR WEIGHT ALCOHOLS AT ELEVATED TEMPERATURE BY PRESENCE THEREIN OF A SYNERGISTIC STABILIZING MIXTURE OF A MONONITROALKANE AND AN EPOXY RESIN. SAID COMPOSITIONS INCLUDING A LOWER MOLECULAR WEIGHT ALCOHOL ARE USEFUL AS SOLVENT MEDIA FOR METAL CLEANING AND DRY CLEANING OF TEXTILES.
