Title (EN) AZEOTROPE-LIKE COMPOSITION OF 1,1,1,3,3-PENTAFLUOROPROPANE AND HYDROGEN FLUORIDE
(FR) COMPOSITION DE TYPE AZEOTROPE DE 1,1,1,3,3-PENTAFLUOROPROPANE ET DE FLUORURE D'HYDROGENE
Abstract: front page image
(EN)Provided are azeotropic and azeotrope-like mixtures of 1,1,1,3,3-pentafluoropropane (HFC-245fa) and hydrogen fluoride. Such are useful as an intermediate in the production of HFC-245fa. The latter is useful as a nontoxic, zero ozone depleting fluorocarbon useful as a solvent, blowing agent, refrigerant, cleaning agent, aerosol propellant, heat transfer medium, dielectric, fire extinguishing composition and power cycle working fluid.
(FR)L'invention concerne des mélanges azéotropes et de type azéotrope de 1,1,1,3,3-pentafluoropropane (HFC-245fa) et de fluorure d'hydrogène, utiles comme intermédiaires dans la production de HFC-245fa. Ce dernier est un fluorocarbure non toxique qui ne détruit pas la couche d'ozone, utile comme solvant, agent d'expansion, réfrigérant, agent nettoyant, propulseur d'aérosol, milieu de transfert thermique, diélectrique, agent extincteur et fluide moteur pour cycle de puissance.
