Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania heterogenicznych katalizatorów racemizacji, który charakteryzuje się tym, że wstępnie ogrzaną do temperatury 550°C mezoporowatą piankę krzemionkową ogrzewa się ponownie w temperaturze co najmniej temperatury 700°C, po czym dodaje się (trialkilosililo)alkiloaminę a po wysuszeniu i ochłodzeniu dodaje się chlorek 4-(chlorometylo)benzoilu, po czym tak przygotowane podłoże ogrzewa się z kompleksem chlorodikarbonyl (pentafenylocyklopentadienylo)ruten(II) w temperaturze co najmniej 110°C.
