| titleOfInvention | improved process for carbamate preparation |
| abstract | A process for the preparation of n- (dialkylaminoalkyl) -carbamic acid esters, in particular propyl (n- [3- (dimethylamino) propyl] carbamate) comprising an oxidative carbonylation reaction of a compound of general structure (ii) (ii) wherein each of r1 and r2, equal to or different from each other, are independently selected from an alkyl group having 1 to 10 carbon atoms, which is optionally substituted by at least one halogen atom, an aryl group or an aralkyl group; R3 is selected from an alkyl group having 1 to 36 carbon atoms, which is optionally substituted by at least one halogen atom, an aryl group or an aralkyl group; each of r ', r and r 4, equal to or different from each other, are independently selected from h, an alkyl group having 1 to 10 carbon atoms, which is optionally substituted by at least one halogen atom, an aryl group or an aralkyl group; and n is an integer in the range 1 to 8, with a hydroxyl compound of formula (iii), r3-oh (iii) and in the presence of a catalyst system. |
