  • Processes for preparing isocyanate functional 1,3,5-triazines and derivatives thereof
    Patent number: 5792864
    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.
