Preferred process aspects involve converting C2-C6 olefin in a cis-form to a trans-form under conditions effective to convert at least about 50 percent, and even more preferably at least about 70 percent, of the cis-form compound to the trans-form compound. In preferred embodiments the C2-C6 olefin comprises tetrafluoropropene, with cis-1,3,3,3 tetrafluoropropene (cis-HFO-1234ze) being converted, preferably at high conversion rates and high selectivity, to trans-1,3,3,3 tetrafluoropropene (trans-HFO-1234ze). In preferred embodiments the conditions effective to achieve the desired high levels of conversion and selectivity include exposing the feed to a metal based catalyst selected from the group consisting of halogentated metal oxides, Lewis acid metal halides, zero-valent metals, and combinations of these, preferably under reaction conditions, including reaction temperature and residence time, effective to convert at least about 5% of the cis-form of the compound to other compounds and to further achieve a selectivity to the trans-form of the compound of at least about 70%.

摘要： A process for producing hydrofluorocarbon compounds represented by the following formula: CF3CHFCHm+1Fn wherein m is 0 or 2; n is 0 or 2; and m+n=2. The process has the step of contacting, i.e., reacting, hydrogen with a precursor compound represented by the following formula: CF3CF═CHmFn wherein m is 0 or 2; n is 0 or 2; and m+n=2. The contact is carried out in the presence of a solid catalyst and in the presence or absence of an inert gas. The catalyst is selected from the group consisting of: Fe, Co, Ni, Cu, Cr, Ru, Rh, Ag, Re, Os, Ir, Pt, Au, Sn, and any combinations thereof. For the hydrogenation of 1234yf to 254eb, Pd can also be used as catalyst in addition to the other above-referenced metals. These metals are preferably supported on a carrier such as activated carbon.

摘要： Disclosed are improved fluorination processes and fluorine-containing compositions which involve introducing to one or more fluorination process compositions a water reactive agent in an amount and under conditions effective to decrease the amount of water in that composition. The water reactive agent is preferably introduced to the fluorination reaction process at a location proximate to the site of the fluorination reaction, or upstream of the fluorination reaction, in amounts and under conditions effective to produce a relatively lower concentration of water in the composition, and preferably throughout the fluorination process.
