    摘要: A process is disclosed for reducing the amount of monofluoroacetate. The process involves (a) contacting a hydrofluorocarbon with a reactant basic aqueous solution to produce an organic phase solution containing a hydrofluoroolefin and an aqueous phase solution containing a monofluoroacetate; and (b) heating the aqueous phase solution to an effective temperature to reduce the amount of monofluoroacetate in the aqueous phase solution, wherein fluoride concentration in the aqueous phase solution is substantially high. Another process is disclosed for reducing the amount of monofluoroacetate. The process involves (a) contacting a first batch of hydrofluorocarbon with a first batch of reactant basic aqueous solution to produce a first batch of organic phase solution containing a hydrofluoroolefin and a first batch of aqueous phase solution containing a monofluoroacetate; (b) separating the first batch of organic phase solution from the first batch of aqueous phase solution; (c) mixing a second batch of hydrofluorocarbon and a second batch of reactant basic aqueous solution with the separated first batch of organic phase solution to produce a second batch of organic phase solution containing a hydrofluoroolefin and a second batch of aqueous phase solution containing a monofluoroacetate; (d) combining the first batch of aqueous phase solution with the second batch of aqueous phase solution; and (e) heating the combined aqueous phase solutions to an effective temperature to reduce the amount of monofluoroacetate in the combined aqueous phase solutions, wherein fluoride concentration in the combined aqueous phase solutions is substantially high.
