Claims (2)

1. Способ получения фторсодержащих олефинов формулы R1-C(CH3)=CH2, где R1=CF3CFHCF2- или HCF2CF2-, заключающийся в нагревании смеси полифторированного спирта формулы R2-С(СН3)2OH, где R2=R1 и концентрированной серной кислоты, отличающийся тем, что процесс проводят в присутствии цеолитов, взятых в количестве 1-40% от массы загруженного спирта, при мольном соотношении серная кислота: полифторированный спирт 0,5-1:0,3-0,5 и температуре 40-120°С.1. The method of producing fluorine-containing olefins of the formula R 1 -C (CH 3 ) = CH 2 , where R 1 = CF 3 CFHCF 2 - or HCF 2 CF 2 -, which consists in heating a mixture of polyfluorinated alcohol of the formula R 2 -C (CH 3 ) 2 OH, where R 2 = R 1 and concentrated sulfuric acid, characterized in that the process is carried out in the presence of zeolites taken in an amount of 1-40% by weight of the loaded alcohol, with a molar ratio of sulfuric acid: polyfluorinated alcohol of 0.5-1: 0.3-0.5 and a temperature of 40-120 ° C. 2. Способ по п.1, отличающийся тем, что 0,5-1,0 моля концентрированной серной кислоты загружается в реакционный сосуд после нагрева смеси 0,3-0,5 молей полифторированного спирта с 0,5-20 г цеолитов до температуры начала реакции.2. The method according to claim 1, characterized in that 0.5-1.0 moles of concentrated sulfuric acid is loaded into the reaction vessel after heating a mixture of 0.3-0.5 moles of polyfluorinated alcohol from 0.5-20 g of zeolites to a temperature the beginning of the reaction.
