- the industrial production of alcohols is often based on starting materials containing carbonyl groups, such as aldehydes, ketones, carboxylic acids, carboxylic anhydrides and esters, which are hydrogenated with hydrogen.
- the production of ethers and lactones is often based on carboxylic acids, esters or anhydrides thereof, lactones or mixtures thereof.
- EP-A-0 848 991 describes a catalyst containing palladium, silver, rhenium and iron which, for example, can hydrogenate maleic acid or its ester to give butanediol.
- a selectivity to butanediol of 89.5% is achieved.
- the hydrogenation success is diminished by the fact that the byproduct is ether tetrahydrofuran (THF) with 5.6%.
- THF ether tetrahydrofuran
- n-butanol is formed as a further by-product.
- 5,698,749 describes catalysts which contain an element from Group VIII and at least rhenium, tungsten or molybdenum on an oxidatively pretreated carbon support.
- Pd / Re / C or Pd / Re / Ag / C catalysts are described.
- hydrogenation of aqueous maleic acid in turn produces, in addition to butanediol, THF.
- Butane diol is obtained with up to 92.8% selectivity.
- THF is still 1.6%
- the other by-product n-butanol is 4.6%.
- US 5,478,952 relates to the hydrogenation of maleic acid on an Ru / Re activated carbon catalyst to form THF and gamma-butyrolactone as main products. - 3 -
- EP-A-0 276 012 relates to the hydrogenation of maleic acid to gamma-butyrolactone and butanediol over P ⁇ VRe / TiO 2 catalysts.

- carbonyl compounds can be catalytically hydrogenated to the corresponding alcohols without ether formation at low temperatures (preferably below 140 ° C.) by using at least rhenium or rhenium / platinum on non-oxidatively treated carbon supports such as activated carbon for the hydrogenation. Without ether formation, this means that the ether formation should have a maximum of 0.5% of the hydrogenation products.
- the ether content is preferably below 0.2%, particularly preferably below 0.1%.
- a non-oxidative treatment of the carbon support material with mineral acids or bases can furthermore be regarded as advantageous compared to an oxidative treatment with ENT or peroxides, since an oxidative pretreatment of activated carbons with H 2 O or peroxides is an expensive pretreatment process, which increases the catalyst production costs considerably.
- oxidative pretreatment with ENT nitrous gases are generated which have to be removed in complex exhaust gas cleaning processes (DeNOX).
- DeNOX complex exhaust gas cleaning processes
- Another disadvantage of the oxidative pretreatment is the loss of material due to the oxidative pretreatment.
- the carbon-containing carrier materials partially dissolve in the oxidizing agents and moldings can even completely disintegrate at the appropriate temperature.
- the commercially available activated carbons are generally suitable as activated carbons. Preference is given to using those which contain little chlorine and sulfur and whose proportion of micropores is as small as possible in relation to the proportion of mesopore and macropores.
- the non-oxidative treatment of the activated carbons can be carried out by treatment with solvents such as water or alcohols.
- the carbon carrier can also be conditioned by non-oxidative treatment with mineral acids such as HC1, H 3 PO 4 , H 2 SO 4, HBr or HF.

- Coal carriers that have been pretreated with solutions of bases such as NH 4 OH, NaOH or KOH also have a positive effect on the catalytic performance.
- the active carbon can be treated with the non-oxidizing agent before or during the application of the platinum and rhenium component or other catalyst components.
- catalysts are used in which the activated carbon carrier is first pretreated non-oxidatively and then oxidatively. In a further particular embodiment, catalysts are used in which the activated carbon carrier is first pretreated oxidatively and then non-oxidatively.
- the activated carbon carrier is stirred in the pretreatment agent at elevated temperature (50 to 90 ° C.).
