A process for making a fluorinated product comprising contacting an alcohol with 1,1,2,2-tetrafluoroethyl-N,N-dimethylamine to produce a product mixture containing the fluorinated product and N,N-dimethyl difluoroacetamide, quenching the product mixture in water to form a first organic phase and an aqueous phase, recovering fluorinated product by separating the first organic phase from the aqueous phase, treating the aqueous phase to recover N,N-dimethyl difluoroacetamide, and converting recovered N,N-dimethyl difluoroacetamide to 1,1,2,2-tetrafluoroethyl-N,N-dimethylamine.
用一种方法制备氟化产品,包括将醇与1,1,2,2-四氟乙基-N,N-二甲胺接触,以产生含有氟化产品和N,N-二甲基二氟乙酰胺的产物混合物,将产物混合物在水中淬灭,形成第一有机相和水相,通过将第一有机相与水相分离来回收氟化产品,处理水相以回收N,N-二甲基二氟乙酰胺,并将回收的N,N-二甲基二氟乙酰胺转化为1,1,2,2-四氟乙基-N,N-二甲胺。
