Document Type and Number:
WIPO Patent Application WO2006017656
Kind Code:
A3
Abstract:
The invention relates to azeotropic and azeotrope-like mixtures of 1,1,1,3,3-pentachloropropane (HCC-240fa) and carbon tetrachloride and a process for separating the azeotrope-like mixtures. The compositions of the invention 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 and aerosol propellant.
