titleOfInvention |
Silica-based zinc catalysts. their preparation and use in the alkoxycarbonylation of amines |
abstract |
The present invention relates to silica-based heterogeneous zinc compounds which are suitable as catalysts in the reaction of amines with dialkyl carbonates to produce carbamates. The catalysts have the formula [SiO 2 ]-CH 2 -CHR-X-COOZn[Y], wherein [SiO 2 ] represents a silica carrier selected from the group consisting of ordered mesoporous silica and irregular amorphous narrow pore silica, R represents a moiety selected from the group consisting of hydrogen, -CH 3 , and -CH 2 CH 3 , preferably hydrogen, X is an aliphatic chain of 2 to 11 carbon atoms that optionally comprises ether moieties and [Y] represents a mono anion. The invention is also directed towards a method for the preparation of the aforementioned compounds and towards method for the alkoxycarbonylation of amines. |
