摘要:
The present invention provides a process for preparing a supported catalyst (catalyst C) having a support (support S) selected from among oxides, phosphates, silicates, carbides, borides and nitrides of main group elements and elements of transition groups VI and II and mixtures of the abovementioned compounds and an active component (activator A) comprising one or more compounds containing one or more elements of transition groups V, VI and VII customary for the catalysis of metathesis reactions.
摘要:
Process for preparing a compound having a nonaromatic C—C double or triple bond (compound A) from another compound or a mixture of other compounds having a nonaromatic C—C double or triple bond (compound B), which comprises bringing the compound (B) into contact with a heterogeneous catalyst comprising carbides or oxycarbides of a transition element at from 50 to 500° C.
