| abstract |
The invention relates to a method for preparing an alkanolic reaction mixture, which results during the production of alkoxycarbonyl amino triazines, contains at least one alkoxycarbonyl aminotriazine, at least one cyclic and/or acyclic carbonic ester, at least one C<SUB>1</SUB>-C<SUB>13</SUB> alkanol optionally containing one or two oxygen atoms as an ether bond and optionally being substituted by C<SUB>1</SUB>-C<SUB>4</SUB> alkyl and/or hydroxy, and which contains at least one alkaline or alkaline earth alkanolate, optionally melamine and, optionally, a catalyst. In the first step, the alkanolic reaction mixture is neutralized by adding acid. The salts arising due to the neutralization are removed in a first variant of the method by extracting them with a polar extracting agent that cannot be mixed with the organic phase whereby obtaining an alkanolic phase containing at least one alkoxycarbonyl amino triazine and a polar extracting agent with salts dissolved therein. In a second variant of the method, the salts arising due to the neutralization are removed by ion exchange on a cation exchanger and/or anion exchanger. |
