Description
  • Byl vyvinut nový mnohostranně použitelný heterogenní katalyzátor metatéze olefinů – oxid rhenistý nanesený na organizované mezoporézní alumině. Tento katalyzátor je vhodný pro metatéze lineárních alkenů, .alpha.-,.omega.-dienů, rovněž na polymerace cykloalkenů metatézí za otevření kruhu a na kometatéze cykloalkenů s lineárními alkeny. Tento katalyzátor pracuje za mírných reakčních podmínek a jeho aktivita je mnohem vyšší než aktivita příslušného katalyzátoru založeného na konvenční alumině. Katalyzátor může být použit opakovaně a může být lehce reaktivován. Byl potvrzen vliv velikosti pórů katalyzátoru na aktivitu i selektivitu jednotlivých reakcí. (cs)
  • A new versatile heterogeneous catalyst for olefin metathesis based on rhenium (VII) oxide supported on organized mesoporous alumina was developed. This catalyst is suitable for metathesis of linear olefins, alpha-, omega-dienes as well as ring-opening metathesis polymerization of cycloalkenes and cross-metathesis of cycloolefins with linear olefins. This catalyst was found to operate under mild reaction conditions and its activity was much higher than that of corresponding catalyst based on conventional alumina. Catalyst can be used repeatedly and can be easily reactivated. Influence of the catalyst pore size on activity as well as selectivity in individual methathesis reactions was established.
