Beschreibung
Zusammenfassung:The invention discloses novel saccharide bio-based cyclic phosphorus/phosphonate as well as a preparation method and application thereof, and belongs to the field of compounds. The cyclic phosphorus/phosphonate is prepared by the following steps: reacting D-xylose with acetyl chloride to obtain an intermediate product, and then reacting with dichlorophosphate or phosphonic dichloride under the action of an acid-binding agent to obtain a target product. The preparation method is high in yield, simple in process, low in raw material cost and small in environmental pollution, and the prepared cyclic phosphorus/phosphonate flame retardant is outstanding in flame retardance and easy to industrialize. 本发明公开了一种新型糖类生物基环状磷/膦酸酯及其制备方法和应用。属于化合物领域。所述的环状磷/膦酸酯是将D-木糖与乙酰氯进行反应得到中间产物,之后在缚酸剂的作用下与二氯磷酸酯或膦酰二氯进行反应,即可得到目标产品。该制备方法产率高,工艺简单,原料成本较低,环境污染小,且制备出的环状磷/膦酸酯阻燃剂阻燃性能突出,易于实现工业化。
