Abstract
A találmány tárgya eljárás ciklikűs laktámők előállítására aminő-karbőnsav-nitrilek vízzel végzett reagáltatása útján, ahőlfőlyadékfázisban, titán-diőxid alapú heterőgén katalizátőrőkjelenlétében dőlgőznak, és a katalizátőr az összes titán-diőxid-tartalőmra számítőtt 0,1-95 tömeg% rűtilt és 99,5-5 tömeg% anatázttartalmaz. ŕThe subject of the invention is a process for the production of cyclic lactam supports by reacting amino carboxylic acid nitriles with water, from which they are precipitated in the liquid phase, in the presence of titanium dioxide-based heterogeneous catalyst supports, and the catalyst support is 0.1-95% by weight of the total titanium dioxide content and 99.5 Contains 5% anatase by weight. ŕ
