  A vic-dichloro-fluorinated alkene of the formula: R1-CCl=CCl-R2, and a fluorinated alkane of the formula: R1-CR3R4-CR5R6-R2, wherein each of R1 and R2 independently represents a perfluoroalkyl group or both of R1 and R2 form together a perfluoroalkylene group, and R3, R4, R5 and R6 independently represent hydrogen or fluorine, are produced from an inexpensive raw material. More specifically, hexachlorocyclopentadiene is reacted with gaseous chlorine using an antimony catalyst, and then the reaction product is reacted with hydrogen fluoride to give 1,2-dichlorohexafluorocyclopentene. Thus-obtained compound is either (i) hydrogenated, or (ii) treated with a fluorinating agent to substitute the chlorine atoms by fluorine atoms, and then hydrogenated, to give the intended fluorinated alkane.

  式中的沧二氯氟化烯：R1-CCl=CCll-R2，以及式中的氟化烷烃：R1-CR3R4-CR5R6-R2，其中 R1 和 R2 各自独立地代表全氟烷基或 R1 和 R2 共同形成全氟烯基，R3、R4、R5 和 R6 各自独立地代表氢或氟。更具体地说，使用锑催化剂使六氯环戊二烯与气态氯反应，然后使反应产物与氟化氢反应，得到 1,2-二氯六氟环戊烯。这样得到的化合物(i)经过氢化，或(ii)经过氟化剂处理，用氟原子代替氯原子，然后再氢化，就得到了所需的氟化烷烃。

  The invention relates to a method for preparing a fluorinated product that is a first perhalogenated five-membered cyclic compound (e.g., 1,2-dichlorohexafluorocyclopentene and 1,1-dichlorooctafluorocyclopentane). This method includes reacting in a gas phase a starting material that is a second perhalogenated five-membered cyclic compound having at least one unsaturated bond, at substantially the same time with chlorine and hydrogen fluoride, in the presence of a fluorination catalyst containing an activated carbon optionally carrying thereon a metal compound, thereby to decrease the number of the at least one unsaturated bond and to increase the number of fluorine atoms of the second compound. The method is appropriate for the production of the first perhalogenated five-membered cyclic compound in an industrial scale.

  本发明涉及一种制备氟化产物的方法，该氟化产物是第一种全卤化五元环化合物（如1,2-二氯六氟环戊烯和1,1-二氯八氟环戊烷）。该方法包括在气相中，在含有活性炭的氟化催化剂（活性炭上可选择携带金属化合物）存在的情况下，使具有至少一个不饱和键的第二种全卤化五元环状化合物与氯和氟化氢基本同时反应，从而减少至少一个不饱和键的数量，增加第二种化合物的氟原子数。该方法适用于工业化生产第一种全卤化五元环状化合物。

  Provided is a manufacturing method in which 1-chloroheptafluorocyclopentene is brought into contact with an alkali metal fluoride to obtain octafluorocyclopentene. The manufacturing method includes a fluorination step of maintaining, at 85° C. or higher, a suspension containing an alkali metal fluoride suspended in a mixed solvent including a polar aprotic solvent and a glycol ether having a higher boiling point than the polar aprotic solvent while supplying 1-chloroheptafluoropentene into the suspension and performing fluorination thereof to obtain octafluorocyclopentene.

  本发明提供了一种制造方法，在该方法中，1-氯七氟环戊烯与碱金属氟化物接触，从而获得八氟环戊烯。 该制造方法包括以下氟化步骤：将含有碱金属氟化物的悬浮液保持在 85° C 或更高温度，该悬浮液悬浮在混合溶剂中，混合溶剂包括极性非沸点溶剂和沸点高于极性非沸点溶剂的乙二醇醚，同时向悬浮液中加入 1-氯七氟环戊烯，并对其进行氟化，以获得八氟环戊烯。
