The invention relates to a method for treating a shear-thinning residue composition deriving from the synthesis of an aryl ether ketone, the residue composition including a liquid fraction and solid residues, the method including the steps of: passing said shear-thinning residue composition through a shear-generating evaporating device, between a rotating part and a stationary part; and recovering a condensed liquid fraction and separately recover concentrated solid residues.
本发明涉及一种处理芳基醚酮合成过程中产生的剪切稀化残留物组合物的方法,该残留物组合物包括液体部分和固体残留物,该方法包括以下步骤:将所述剪切稀化残留物组合物通过旋转部分和固定部分之间的剪切蒸发装置;回收冷凝的液体部分,并分别回收浓缩的固体残留物。
