Abstract

A catalytic process is disclosed for producing fluorine-substituted hydrocarbon products of the formulae RCH2CF2R and RFC=CHR at an elevated temperature, from compounds of the formula RCHFCHFR, where each R is independently selected from the group consisting of -CF3, -CF2CF3 and -CF2CF2CF3 or where both R groups of a formula together are -(CF2)2-, -(CF2)3- or -(CF2)4-. Suitable catalysts include carbon catalysts and catalysts containing at least one compound of a selected metal (e.g., Na, K, Rb, Cs, Y, La, Ce, Pr, Nd, Sm, Cr, Fe, Co, Rh, Ni, Cu, and/or Zn) supported on carbon. The saturated gem-dihydro-products may also be produced by hydrofluorinating the corresponding olefinic product over such catalysts at an elevated temperature, and can be combined with various other miscible solvents to form compositions useful for cleaning. Compounds such as CF3CF2CH2CF2CF3, CF3CF2CH2(CF2)2CF3, CF3CH=CF(CF2)2CF3, CF3CF=CH(CF2)2CF3, CF3CF2CH2(CF2)3CF3, CF3(CF2)2CH2(CF2)2CF3,CF3CH=CF)CF2)3CF3, CF3CF=CH(CF2)3CF3, CF3(CF2)2CH2(CF2)3CF3, CF3CF2CH2(CF2)4CF3, CF3CH=CF(CF2)4CF3, CF3CF=CH(CF2)4CF3, CF3CF2CH=CF(CF2)3CF3, CF3CF2CF=CH(CF2)3CF3 and (a) azeotropic compositions such as azeotrops of CH3CH2CF2CF2CF3 and/or CF3CF2CH2CF2CF3 with methanol, ethanol, or isopropanol are disclosed.
