Abstract
This invention relates to a process for the preparation of triazine carbamates by reacting a mixture of an aminotriazine A having at least two amino groups per molecule, an organic carbonate C, and a base B selected from the group consisting of alkoxides, and arylalkoxides of metals M, which may be alkali or earth alkali metals, and a solvent S which is a monohydric alcohol solvent R2OH or a mixture of solvents that comprises a monohydric alcohol R2OH, and a monohydric alcohol R3OH, or a mixture of solvents that comprises a monohydric alcohol R2OH with a further solvent selected from the group consisting of ether, alcohol, and hydrocarbon solvents, and adding to the products of the said reaction, an acid or a solution of an acid in a solvent.
