| 摘 要： | 研究了一种改进的双季戊四醇重结晶工艺,使双季戊四醇的灰份从0.1%以上降至0.05%以下,纯度从80%提高到85%以上,收率比传统重结晶工艺提高10%左右,且成本下降,操作更简便。实验确定的优化工艺条件为:溶解水量1:5～6、溶解水温度60℃、结晶冷却时间6～8h、离心分离温度20℃。

| Abstract: | A new technology for recrystallized of DPE was studied, the ash cotent of DPE was reduced from 0.1% to 0.05%, the purity of DPE was inproved from 80% to 85%, the total yield is ligher 10% than that old technology. The optimal coditions was follow as :dissolve water multiple 1:5～6: water temperature 60℃;crystallize cooling time 6-8hours; centrifugal temperature 20℃. |
