Appeal No. 1997-3045
Application 08/286,835
THE INVENTION
Appellants claim a process for making a carboxylated
amino-1,3,5-triazine by reacting an amino-1,3,5-triazine
having a recited formula with carbon dioxide in the presence
of a base. Claim 21 is illustrative and reads as follows:
21. 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 NH group
2
or an oligomer thereof, the amino-1,3,5-triazine being
represented by the general formula
wherein Z and Z are independently selected from the group1
consisting of hydrogen, a hydrocarbyl, a hydrocarbyloxy and a
group represented by the formula - N(Q) , and
2
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.
