Description

Изобретение относитс  к способу получени  безводных дифторидов меди и никел . Известен способ получени  безводных дифторидов меди и никел  при взаимодействии СОЛИ соответству он1его металла с фто л-1СтЫМ 5 водородом. К недостаткам известного способа относ тс  проведение процесса при высоких температурах в присутствии фтористого водорода, вызывающего коррозию аппаратуры.10 С целью упрощени  способа предлагаетс  в качестве фторсодержащего реагента использовать четырехфтористую серу, предпочтительно в п тикратном избытке к соли металла .15 Образующуюс  серу удал ют путем промывани  продуктов реакции сероуглеродом или бензолом или отгонкой. Реакцию провод т при 200-220°С. Пример 1. 4 Г просушенного при 110°С 20 сульфида меди помещают в автоклав емкостью 100 мл, охлаждают его жидким азотом , эвакуируют и конденсируют в него 20 г технической четырехфтористой среды. Автоклав нагревают 20 час при 190-200°С. Твер- 25 ый продукт после промывки безводным сероуглеродом представл ет собой чистый ди- фторид меди. Найдено, %: Си 61,8; F 38,0. Вычислено, %: Си 62,57; F 37,43. Пример 2. Из 6 гпросущенногопри 110° С сульфида никел  и 30 г технической четырехфтористой серы аналогично примеру 1 в течение 20 час при 200-220°С получают чистый дифторид никел  с выходом Найдено, %; Ni 60,1; F 38,9. Вычислено, %: Ni 60,77. Предмет изобретени  1.Способ получени  безводных дифторидов меди и никел  путем взаимодействи  соли соответствующего металла с фторсодержащим реагентом при нагревании, отличающийс  тем, что, с целью унрощени  способа, в качестве фторсодержащего реагента используют четырехфтористую серу. 2.Способ по п. 1, отличающийс  тем, что четырехфтористую серу берут в п тикратном избытке к соли металла.This invention relates to a process for the preparation of anhydrous copper and nickel difluorides. A known method for the preparation of anhydrous copper and nickel difluorides by the interaction of the SALT of the corresponding metal with fluoro-1 STIM 5 hydrogen. The disadvantages of this method include carrying out the process at high temperatures in the presence of hydrogen fluoride, corrosive apparatus.10 In order to simplify the process, sulfur tetrafluoride is used as a fluorine-containing reagent, preferably in five-fold excess metal salt. 15 The resulting sulfur is removed by washing reaction products by carbon disulfide or benzene or distillation. The reaction is carried out at 200-220 ° C. Example 1. 4 g of copper sulfide, dried at 110 ° C, are placed in a 100 ml autoclave, cooled with liquid nitrogen, evacuated and 20 g of technical fluoro-fluoride is condensed into it. The autoclave is heated for 20 hours at 190-200 ° C. The solid product after washing with anhydrous carbon disulfide is pure copper difluoride. Found,%: C 61.8; F 38.0. Calculated,%: C 62,57; F 37.43. Example 2. From 6 g of permissible gas at 110 ° C of nickel sulfide and 30 g of technical sulfur tetrafluoride as in Example 1, pure nickel difluoride is obtained in 20% at 20-220 ° C with a yield of%; Ni 60.1; F 38.9. Calculated,%: Ni 60,77. The subject of the invention 1. A method for producing anhydrous copper and nickel difluorides by reacting a salt of an appropriate metal with a fluorine-containing reagent by heating, characterized in that, in order to simplify the process, sulfur tetrafluoride is used as the fluorine-containing reagent. 2. A method according to claim 1, characterized in that sulfur tetrafluoride is taken in fivefold excess to the metal salt.
