摘要： The present invention pertains to a novel process of manufacturing the compound 2,3,3,3-tetrafluoropropene (1234yf). The compound 1234yf is the newest refrigerant with zero OPD (Ozone Depleting Potential) and zero GWP (Global Warming Potential). Thus, the invention relates to a process, involving a carbine generation route, for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf), of the compound 243db (2,3-dichloro-1,1,1-trifluoropropane), and optionally of the compound 2-chloro-1,1,1-trifluoropropene (1233xf) via carbene route and compound 243db (2,3-dichloro-1,1,1-trifluoropropane). The invention also relates to a process for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf), wherein the compound 243db (2,3-dichloro-1,1,1-trifluoropropane) serves as a starting material, for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf). Further, the invention relates to a process for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf), and of the compound 243db (2,3-dichloro-1,1,1-trifluoropropane), wherein the initial starting materials are selected from the group consisting of compound 123 (2,2-dichloro-1,1,1-trifluoroethane), compound 124 (2-chloro-1,1,1,2-tetrafluoroethane), and compound 125 (pentafluoroethane). The compound 123 (2,2-dichloro-1,1,1-trifluoroethane is preferred as the initial starting material. In particular, the process of the invention involves a carbene generation step, and wherein the carbene formed is further reacted towards the targeted compounds of the invention, especially towards the compound 243db (2,3-dichloro-1,1,1-trifluoropropane), and finally towards the compound 2,3,3,3-tetrafluoropropene (1234yf).

摘要： The invention relates to a use of a fluorination gas, wherein the elemental fluorine (F 2 ) is preferably present in a high concentration, for example, in a concentration of elemental fluorine (F 2 ), especially of equal to much higher than 15 % or even 20 % by volume (i.e., at least 15 % or even 20 % by volume), and to a process for the manufacture of a fluorinated benzene starting from benzoic acid by direct fluorination employing a fluorination gas, wherein the elemental fluorine (F 2 ) is preferably present in a high concentration, and subsequent decarboxylation of the benzoic acid hypofluorite obtained by direct fluorination. The process of the invention is also directed to the manufacture of a benzoic acid hypofluorite by direct fluorination of benzoic acid. Especially the invention is of interest in the preparation of fluorinatedbenzene, final products and as well intermediates, for usage in agro-, pharma-, electronics-, catalyst, solvent and other functional chemical applications. The fluorination process of the invention may be performed batch-wise or in a continuous manner. If the process of the invention is performed batch-wise, a column (tower) reactor may be used. If the process of the invention is continuous a micro reactor may be used. The invention is characterized in that the starting compound is benzoic acid, and the fluorinated compound produced is a benzoic acid hypofluorite obtained by direct fluorination, which benzoic acid hypofluorite can be converted by decarboxylation to a fluorinated benzene, preferably monofluorobenzene.
