    摘要: To provide a method for efficiently separating 2,3,3,3-tetrafluoropropene (HFO-1234yf) and chloromethane (R40) from a composition containing HFO-1234yf and R40. A method for separating HFO-1234yf containing substantially no R40, which comprises bringing an azeotropic composition or azeotrope-like composition of H FO-1234yf and R40 into contact with a specific extraction solvent.

    摘要: Methods and assemblies for improving the reaction kinetics of, conserving reactants utilized in, and/or producing a more pure reaction product of, liquid-phase reactions that involve volatile reactants and products are provided. The methods and assemblies herein provide for a feed of reaction liquid to two or more absorption zones, wherein the temperature and/or feed rate of the liquid is independently adjusted prior to introduction into at least one of the two or more absorption zones. More particularly, the temperature and feed rate of the liquid as delivered to each absorption zone can be adjusted independently to optimize the absorption of at least a portion of any gaseous reactants and byproducts from the gaseous product stream and/or to optimize reaction zone conditions. Reaction kinetics may thus be improved, or substantially maintained.

    摘要: A reactor with swing feeds is provided for oxychlorination. This reactor comprises multiple inlets with controls capable of introducing feed streams sequentially to the reactor. In one configuration, a feed stream comprises a paraffin or olefin hydrocarbon such as methane or ethylene, and a second feed stream comprises oxygen and hydrogen chloride. By segregating these feeds, combustion reactions can be minimized and yields of chlorinated components increased.
