| abstract |
The invention relates to a method for the production of optionally alkyl-substituted THF. The above is obtained by catalytic hydrogenation of C4-dicarboxylic acids and/or derivatives thereof, in the gas phase, using a catalyst containing <80 wt %, preferably <70 wt. %, in particular 10 to 65 wt. % CuO and >20 wt. %, preferably >30 wt %, in particular 35 to 90 wt. % of an oxidic support with acidic centres, whereby the method is carried out with a hot spot temperature of 240 to 280 DEG C and a catalytic loading of 0.01 to 1.0, preferably 0.02 to 1, in particular 0.05 to 0.5 kg reactant/l catalyst.hour. |
