Title (EN) MANUFACTURE OF 1,1,1,2,3,3-HEXAFLUOROPROPANE AND 1,1,1,2-TETRAFLUOROPROPANE VIA CATALYTIC HYDROGENATION
(FR) FABRICATION DE 1,1,1,2,3,3-HEXAFLUOROPROPANE AND 1,1,1,2-TÉTRAFLUOROPROPANE PAR L'HYDROGÉNATION CATALYTIQUE
Abstract: front page image
(EN)A process for producing hydrofluorocarbon compounds represented by the following formula: CF3CHFCHm+1Fn wherein m is 0, 1, or 2; n is 0, 1, 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, 1, or 2; n is 0, 1, 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.
(FR)La présente invention concerne un procédé de production de composés d'hydrofluorocarbone de formule (I): CF3CHFCHm+1Fn dans laquelle m est 0, 1, ou 2; n est 0, 1, ou 2; et m + n = 2. Le procédé comprend l'étape de mise en contact, c'est-à-dire, la réaction, d'hydrogène avec un composé précurseur de formule (II) : CF3CF=CHmFn dans laquelle m est 0, 1, ou 2; n est 0, 1, ou 2; et m + n = 2. La mise en contact est effectuée en présence d'un catalyseur solide et en présence ou absence d'un gaz inerte. Le catalyseur est choisi parmi le groupe constitué de : Fe, Co, Ni, Cu, Cr, Ru, Rh, Ag, Re, Os, Ir, Pt, Au, Sn, et toutes combinaisons de ceux-ci. Pour l'hydrogénation de 1234yf en 254eb, le Pd peut également être utilisé comme catalyseur outre les autres métaux susmentionnés. Ces métaux sont, de préférence, disposés sur un support tel que du charbon actif.
