摘要
以双酚A和三氯氧磷、三聚氰胺为原料合成了双酚A双磷酰三聚氰胺氮-磷复合型阻燃剂。考察了反应温度、反应时间、反应物原料配比对产品收率的影响。结果表明,当第一步反应的反应温度为80℃、反应时间为7h、n(双酚A)∶n(三氯氧磷)为1∶2,第二步反应的反应温度为60℃、反应时间为5h、n(双酚A双磷酰氯)∶n(三聚氰胺)为1∶2时,产品双酚A双磷酰三聚氰胺的平均收率为61.78%,并通过红外光谱和热重分析,表征了产物的结构与性质。
The title product was prepared using bisphenol A,phosphorus oxychloride and melamine as main raw materials.Effects of reaction temperature,reaction time,mole ratio of raw materials on the yield of the product were investigated.The results showed when 80℃,7 h and the mol ratio of phosphorus oxychloride/bisphenol A was 2 in the first reaction,and when 60℃,5 h and the mol ratio of melamine / bisphenol A diphosphonyl chloride was 2 in the second reaction,the average yield of the end product was 61.78%.The structure and properties of the product were characterized by IR spectroscopy and gravitational thermal analysis,respectively.
