中文摘要:
      本文以磷酸和环氧丙烷为原料,在绿色溶剂中以路易斯酸离子液体为催化剂合成了反应型阻燃剂三(2-羟丙基)磷酸酯。利用红外、核磁、质谱对其结构进行表征。研究了催化剂种类及用量,物料比、反应时间和反应温度等因素对反应的影响。结果表明,最佳条件为n(磷酸)∶n(环氧丙烷)=1∶3.2,反应温度90℃,反应时间3h,催化剂用量3%,所得产品的产率可达到92.8%。产品性能指标优良,热重分析表明其稳定性符合材料加工要求。
英文摘要:
      In this paper, phosphoric acid and propylene oxide were used as raw materials, and a reactive flame retardant tris(2-hydroxypropyl) phosphate was synthesized by using a Lewis acid ionic liquid as a catalyst in a green solvent. The structure was characterized by infrared, nuclear magnetic and mass spectrometry. The effects of the type and amount of catalyst, material ratio, reaction time and reaction temperature on the reaction were studied. The results show that the optimum conditions are n (phosphoric acid): n (propylene oxide) = 1:3.2, the reaction temperature is 90 ? C, the reaction time is 3 h, the amount of the catalyst is 3%, and the yield of the obtained product can reach 92.8%. The product performance index is excellent, and the thermogravimetric analysis shows that its stability meets the material processing requirements.
