摘要: Disclosed is a process for making hexafluoro-2-butyne comprising the steps of: (a) providing a composition comprising CF3CX═CXCF3, where X=halogen; and (b) treating CF3CX═CXCF3 with a dehalogenation catalyst in the presence of a halogen acceptor compound Y, where Y is not hydrogen. The halogen acceptor compound Y is a material capable of being halogenated, preferably a compound having a multiple bond, such as an alkyne, alkene, allene, or carbon monoxide. Another suitable material capable of being halogenated is a cyclopropane. A catalyst effectively transfers halogen from CF3CX═CXCF3 to the halogen acceptor compound. Since Y is not hydrogen, the formation of CF3CX═CHCF3 is greatly reduced or eliminated.
摘要翻译: 公开了制备六氟-2-丁炔的方法,包括以下步骤:(a)提供包含CF 3 C X = CXCF 3的组合物,其中X =卤素; 和(b)在卤素受体化合物Y的存在下用脱卤催化剂处理CF 3 C X = CXCF 3,其中Y不是氢。 卤素受体化合物Y是能够被卤化的物质,优选具有多重键的化合物,如炔烃,烯烃,烯烃或一氧化碳。 能够被卤化的另一种合适的材料是环丙烷。 催化剂有效地将卤素从CF 3 C X = CXCF 3转移到卤素受体化合物。 由于Y不是氢,CF3CX = CHCF3的形成大大降低或消除。
