BINARY AZEOTROPIC COMPOSITIONS OF (CF3CHFCHFCH2CF3) WITH METHANOL OR ETHANOL OR ISOPROPANOL.

摘要

A COMPOSITIONS OF THE INSTANT INVENTION COMPRISE ADMIXTURE OF EFFECTIVE AMOUNTS OF 43-10MEE (CF3CHFCHFCH2CF3, BOILING POINT = 50.0°C) WITH AN ALCOHOL SELECTED FROM THE GROUP CONSISTING OF METHANOL (CH3OH, BOILING POINT = 64.7°C) OR ETHANOL (CH3-CH2-OH, BOILING POINT = 78.4°C) OR ISOPROPANOL (CH3-CHOH-CH3, BOILING POINT = 82.4°C) TO FORM AN AZEOTROPIC COMPOSITION. THE AZEOTROPIC COMPOSITIONS COMPRISES ADMIXTURES OF EFFECTIVE AMOUNTS OF 1, 1, 1, 2, 3, 4, 4, 5, 5, 5-DECAFLUOPENTANE (43-10MEE) WITH ETHANOL OR ISOPROPANOL. MORE SPECIFICALLY, THE AZEOTROPIC MIXTURES ARE AN ADMIXTURE OF 89.0 - 99.0 WEIGHT PERCENT 43 - 10MEE AND ABOUT 1.0 - 11.0 WEIGHT PERCENT METHANOL AND AN ADMIXTURE OF ABOUT 1.0 - 7.0 (PREFERABLY 2 - 6) WEIGHT PERCENT ISOPROPANOL. THE SAID AZEOTROPIC MIXTURES ARE USEFUL IN SOLVENT CLEANING APPLICATIONS, AS BLOWING AGENTS, REFRIGERANTS, HEATING MEDIUMS AND AEROSOL PROPELLANTS.
