摘要
以三氯氧磷 (POCl3)、季戊四醇 (PEL)和三聚氰胺 (MEL)为原料 ,研究反应温度、时间及原料加入方式等工艺条件对转化率及产品双氯螺磷收率的影响 ,探讨IFR合成的最佳工艺条件 ,所得结果将为IFR的工业化生产提供理论依据。
Dichloro phosphorspirol and it′s melamine salt have been synthesized using phosphorus oxychloride (POCl 3),pentaerythritol(PEL) and melamine(MEL) as materials.The influence of reaction temperature,reacting time,and the mode of raw material feeding have been inspected and the optimal technological parameters have been confirmed.The results obtained above will provide valid evidence for the commercial production of intumescent flame retardant(IFR).
