| titleOfInvention | Production of a defined mixture of THF, BDO and GBL by gas phase hydrogenation |
| abstract | The present invention is a C 4 dicarboxylic acids and / or gas phase of its derivatives, BDO is alkyl optionally substituted by 2 steps hydrogenation, a method of manufacturing vary the mixture of GBL and THF, a) first in step, in the gas phase, a C 4 dicarboxylic acids and / or gas flow derivatives thereof, over a catalyst at a pressure and 200 to 300 [° C. of the temperature of 2 to 100 bar, in the first reactor, 20 mm 3 Hydrogenation in the presence of a catalyst in the form of a catalyst compact having a volume of less than, forming a stream mainly containing optionally substituted GBL and THF, said catalyst comprising 5 to 95% by weight of copper oxide and A product consisting of 5 to 95% by weight of an oxide having an acidic center, b) separating succinic anhydride optionally formed by partial condensation, and c) a product mostly remaining in the gas phase by partial condensation, THF Water and GBL, at a reduced temperature of a pressure and 150 to 240 ° C. in order to reduce the flow loss of the same pressure or under the hydrogenation circulation, in the second reactor, CuO95 wt% or less, and ZnO, Al 2 From 5 to 95% by mass of one or more oxides selected from the group consisting of O 3 , SiO 2 , TiO 2 , ZrO 2 , CeO 2 , MgO, CaO, SrO, BaO, La 2 O 3 and Mn 2 O 3 To form a stream containing a mixture of BDO, GBL and THF, d) separating the hydrogen from the product and returning it to the hydrogenation, e) the product, THF, BDO, GBL and Water is separated by distillation, optionally a GBL rich stream is returned to the second reactor or optionally discharged, BDO, THF and GBL are worked up by distillation, and two hydrogen Adjusting the ratio of product, THF, GBL and BDO to each other within the ranges of 10-100% THF, GBL 0-90% and BDO 0-90% by weight only by varying the zone and optionally the temperature of the GBL return stream It is characterized by doing. |
