摘要 |
Carrier catalysts (I), useful in the preparation of cycloalkadiene by metathesis reaction, comprises a gamma -alumina as carrier material, rhenium oxide (1-12 wt.%), tin compound (II) or tin dioxide (0-40 wt.%) and at least one modifying agent of phosphorous, cesium or mineral acid. Carrier catalysts (I) useful in the preparation of cycloalkadiene by metathesis reaction, comprises a gamma -alumina as carrier material, rhenium oxide (1-12 wt.%), tin compound (II) of formula (SnR 4) or tin dioxide (0-40 wt.%) and at least one modifying agent of phosphorous, cesium or mineral acid. R 41-8C alkyl. An independent claim is included for the preparation of cycloalkadiene by metathesis reaction comprising reacting a cycloalka-mono-ene, a cyclopolyene and/or acyclic polyene in liquid phase, in the presence of (I). |
