2-联苯基二苯基磷酸酯的合成

2-联苯基二苯基磷酸酯是用苯酚、邻苯基苯酚和三氯氧磷反应制得.通过探讨物料配比、反应温度、反应时间、催化剂种类和用量对反应的影响,确定了反应的最佳条件：三氯化铝作为催化剂,甲苯为溶剂,三氯氧磷∶苯酚∶邻苯基苯酚∶三氯化铝为1.15∶2.45∶1.00∶0.08,加入苯酚后回流反应时间9h.

Synthesis of 2-Biphenylyl Diphenyl Phosphate

2 - biphenyl diphenyl phosphate was synthesized with phenol, o-phenyl phenol and phosphorus oxychloride.The influences of material ratio, reaction temperature, reaction time,type and amount of catalyst on reaction were experimented; the suitable synthesis conditions were determined：aluminum chloride as a catalyst, toluene as a solvent, molar ratio of phosphorus oxychloride, phenol, o-phenyl phenol and aluminum chloride was 1.15：2.45：1.00：0.08.
