Summary:The present invention relates to an improved process for the separation of 2, 4-bis-(2, 4-dihydroxyphenyl)-6-(4-methoxyphenyl)-1, 3, 5-triazine (DIOPAT) from an aqueous mixture N containing DIOPAT wherein the process comprises the steps of: concentrating the aqueous mixture N to obtain an aqueous suspension S1 containing DIOPAT having a solid content; evaporating a solvent from the aqueous suspension S1; and drying the DIOPAT to obtain a solids content of greater than 90 wt.-% based on the total weight of the DIOPAT. 本发明涉及一种用于将2,4-双-(2,4-二羟基苯基)-6-(4-甲氧基苯基)-1,3,5-三嗪(DIOPAT)从含DIOPAT的水性混合物N中分离的改进方法，其中该方法包括以下步骤：使该水性混合物N浓缩以获得具有一定固体含量的含DIOPAT的水性悬浮液S1；使溶剂从该水性悬浮液S1中蒸发；以及使该DIOPAT干燥以获得基于该DIOPAT的总重量大于90wt.-％的固体含量。
