This invention relates to azeotrope-like compositions, methods and systems having utility in numerous applications, and in particular, uses for azeotrope-like compositions comprising effective amounts of the compound cis-1,1,1,4,4,4-hexafluoro-2-butene (Z-HFO-1336mzzm), which has the following structure: and another material selected from the group consisting of water, fluoroketones, alcohols, hydrochlorofluoroolefins, and combinations of two or more thereof. These compositions may be used in a wide variety of applications such as, blowing agents, refrigerants, heating agents, power cycle agents, cleaning agents, aerosol propellants, sterilization agents, lubricants, flavor and fragrance extractants, flammability reducing agents, and flame suppression agents.

A process for preparing 1-chloro-1,1,3,3,3-pentafluoropropane, CF CH CF Cl, comprising contacting in a reaction zone in the substantial absence of oxygen, reactants comprising chlorine and 1,1,1,3,3-pentafluoropropane, CF CH CHF (also referred to as HFC-245fa), and subjecting the reactants to actinic radiation, such as UV light at about 2,000 to 4,000 Angstroms, wherein: (1) inert gas is present at a concentration equal to or less than about 5 wt. % of the total weight of reactants; (2) the molar ratio of chlorine to CF CH CHF is from about 0.2:1 to about 1.5:1; and (3) the concentration of chlorinated product produced having greater than one chlorine present in the molecule is less than or equal to about 10 wt. %.
