  • Publication number: 20190352242
    Abstract: The present disclosure provides separation processes for removing heavy organics that are formed in various production processes of HCFO-1233zd(E). Such separation processes allow for the recovery and/or separation of the heavy organics from reactants that are used to form HCFO-1233zd(E), including HF. Such separation or recovery processes may utilize various separation techniques (e.g., decanting, liquid-liquid separation, distillation, and flash distillation) and may also utilize the unique properties of azeotropic or azeotrope-like compositions. Recovery of the heavy organic that is substantially free from HF may allow for their use in subsequent manufacture processes or disposal.
