摘要:The invention is directed to a simple and new method for the homogeneous synthesis of cellulose ethers. Ionic liquids are not only used as solvent, but also as reaction media for the homogeneous etherification of cellulose. The dissolved cellulose is treated with the etherification agent in the absence of organic and/or inorganic bases and in the absence and/or in the presence of moderate amounts of water. The obtained cellulose ethers show new distributions of substitution on the polymer chain, resulting in new properties and applications.

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 carbene 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), the initial starting materials are selected from the group consisting of com-pound 123 (2,2-dichloro-1,1,1-trifluoroethane), compound 124 (2-chloro-1,1,1,2-tetrafluoroethane), and compound 125 (pentafluoroethane).
