METHOD FOR PREPARING FLUORO-OLEFINS Russian patent published in 2003 - IPC

Abstract RU 2210559 C2

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to preparing fluoro-olefins that are used for preparing fluoro-containing polymers. Method is carried out by interaction of the parent fluorocarbon taken among the group consisting of (CF3)2CFCH2F,(CF3)2CHF,(CF3)2CFOCF2CHF2 and C6H5(CF3)2 in gaseous phase with defluorinating agent. Carbon, copper, iron, nickel or zinc is used as a defluorinating agent. Interaction is carried out at temperature 300-800 C for 1.5-5 h. Olefin fluorocarbon taken among the group: (CF3)2C=CH2,CF3CH=CF2,CF2=C(CF3)OCF2CHF2 and C6H5C(CF3)=CF is prepared as the end product. EFFECT: improved ecological and reduced economical indices of process. 2 cl, 12 ex
