摘要： The invention relates to a process for treating an alcoholic reaction mixture produced during the preparation of alkoxycarbonylaminotriazines and comprising at least one alkoxycarbonylaminotriazine, at least one cyclic and/or acyclic carbonic acid ester, at least one C1-C13-alkanol optionally containing one or two oxygen atoms as ether bond and optionally substituted by C1-C4-alkyl and/or hydroxy, and at least one alkali metal or alkaline earth metal alkoxide, optionally melamine and optionally catalyst, in which polar and/or ionic components are removed by extraction with a polar extractant that is not completely miscible with the organic phase present in the reaction mixture, giving an alcoholic phase comprising at least one alkoxycarbonylaminotriazine, and a polar phase comprising extractant with polar and/or ionic components dissolved therein.
