Abstract
A method for the production of ureas which consists in reacting a nitrogenous organic compound with carbon monoxide in the presence of a catalyst, characterized in that it is brought into contact at elevated temperatures and pressures in a basic solution, a nitrogen-containing organic compound which contains less a non-cyclic group, in which group a nitrogen atom is directly fixed to a single carbon atom and is also fixed through a double bond to an oxygen atom or another nitrogen atom, with carbon monoxide and a compound which is selected from the group consisting of water and another nitrogen-containing organic compound, wherein the nitrogen atom is attached to at least one hydrogen atom in the presence of an active amount of a catalyst selected from the group consisting of selenium, sulfur, compounds containing selenium, organic sulfides and inorganic sulphides and mixtures thereof.
