Claims
- 1. A process for the preparation of 1,4-butanediol, which comprises converting 1,3-butadiene diepoxide in the presence of hydrogen over a hydrogenation catalyst which comprises Ni and which may further comprise one or more elements selected from the group consisting of cobalt, copper, manganese, molybdenum, rhenium, osmium, ruthenium, rhodium and iridium.
- 2. The process defined in claim 1, wherein the hydrogenation catalyst is a heterogeneous hydrogenation catalyst.
- 3. The process defined in claim 2, wherein the hydrogenation catalyst comprises a carrier selected from the group consisting of oxides of aluminium and of titanium, zirconium dioxide, silica, kieselgur, silica gel, aluminas, silicates, zeolites and active carbon.
- 4. The process defined in claim 1, wherein the hydrogenation catalyst comprises a carrier selected from the group consisting of oxides of aluminium and of titanium, zirconium dioxide, silica, kieselgur, silica gel, aluminas, silicates, zeolites and active carbon.
- 5. The process defined in claim 1, which is carried out at from 0 to 300.degree. C. and from 1 to 300 bar.
- 6. The process defined in claim 1, which is carried out in a solvent.
- 7. The process defined in claim 1, wherein the hydrogenation catalyst contains cobalt.
- 8. The process defined in claim 1, wherein the hydrogenation catalyst contains copper.
- 9. The process defined in claim 1, wherein the hydrogenation catalyst contains rhenium.
- 10. The process defined in claim 1, which is carried out at from 60 to 220.degree. C. and from 10 to 250 bar.
