Abstract
The present invention relates generally to carboxylated amino-1,3,5-triazines and the preparation thereof via carboxylation of amino-1,3,5-triazines with carbon dioxide and a base. These carboxylated amino-1,3,5-triazines find use, for example, as intermediates in the production of other useful amino-1,3,5-triazine derivatives, and particularly carbamate and isocyanate functional 1,3,5-triazines. The present invention also relates to the preparation of such carbamate and isocyanate functional 1,3,5-triazines.
Claims20
A process for preparing a carboxylated amino-1,3,5-triazine comprising the step of contacting:
- (i) an amino 1,3,5-triazine having at least one NH2 group or an oligomer thereof, the amino-1,3,5-triazine being represented by the general formula
- wherein Z and Z1 are independently selected from the group consisting of hydrogen, a hydrocarbyl, a hydrocarbyloxy and a group represented by the formula —N(Q)2, and
- each Q is independently selected from the group consisting of hydrogen and a hydrocarbyl;
- (ii) carbon dioxide;
- and
- (iii) a base,
- under reaction conditions sufficient to produce a corresponding carboxylated amino-1,3,5-triazine.
