    • A process for producing 1,1,1,4,4,4-hexafluoro-2-butenes comprising a mixture of 1,1,1,4,4,4-hexafluoro-2,3-dichloro-2-butene, 1,1,1,4,4,4-hexafluoro-2-chloro-2-butene and 1,1,1,4,4,4-hexafluoro-2-butene by the reaction of at least one member selected from among butane, butene and butadiene with chlorine and HF in the presence of a suitable catalyst, and further producing 1,1,1,4,4,4-hexafluorobutane by reducing the above reaction products in the presence of a noble metal catalyst. This process can provide at a high selectivity 1,1,1,4,4,4-hexafluorobutane that is useful as a substitute for HCFC used as a blowing agent, cleaning agent and heat medium, and also provide as the intermediate 1,1,1,4,4,4-hexafluoro-2-butenes in one stage at a low cost in a high yield, said butenes comprising a mixture of 1,1,1,4,4,4-hexafluoro-2,3-dichloro-2-butene, 1,1,1,4,4,4-hexafluoro-2-chloro-2-butene and 1,1,1,4,4,4-hexafluoro-2-butene and being useful as the intermediate industrial chemicals for producing medicines and agricultural chemicals.
    • 制备1,1,1,4,4,4-六氟-2-丁烯的方法,其包含1,1,1,4,4,4-六氟-2,3-二氯-2-丁烯,1 ,1,1,4,4,4-六氟-2-氯-2-丁烯和1,1,1,4,4,4-六氟-2-丁烯,通过选自丁烷中的至少一种 ,丁烯和丁二烯与氯和HF在合适的催化剂存在下,通过在贵金属催化剂的存在下还原上述反应产物进一步制备1,1,1,4,4,4-六氟丁烷。 该方法可以提供高选择性1,1,1,4,4,4-六氟丁烷,其可用作用作发泡剂,清洁剂和热介质的HCFC的替代物,并且还提供作为中间体1,1 ,1,4,4,4-六氟-2-丁烯,以高产率以低成本在一个阶段中,所述丁烯包含1,1,1,4,4,4-六氟-2-丁烯的混合物, 二氯-2-丁烯,1,1,1,4,4,4-六氟-2-氯-2-丁烯和1,1,1,4,4,4-六氟-2-丁烯,可用作 用于生产药物和农药的中间工业化学品。
