Abstract
A találmány tárgya eljárás karbamátok előállítására aromás aminok ésszerves karbonátok reakciója útján. A találmány szerint a reakciótinert hordozóanyagon lévő fémalapú katalizátor jelenlétében végzik. Akatalizátor fémkomponensként előnyösen titán-, cink-, cirkónium-, ón-vagy ólomvegyületet tartalmazhat. A találmány tárgya továbbákatalizátor, amely szerves fémsót tartalmaz inert hordozóra felvittállapotban. ÓThe subject of the invention is a process for the production of carbamates by the reaction of aromatic amines and organic carbonates. According to the invention, the reaction thinner is carried out in the presence of a metal-based catalyst on a support material. Catalyst can preferably contain a titanium, zinc, zirconium, tin or lead compound as a metal component. The subject of the invention is also a catalyst that contains an organic metal salt applied to an inert support. HE
