摘要
以苯酚、六氯环三磷腈(HCTP)、氢氧化钠为原料合成了苯氧基环三磷腈(PCPZ),考察了苯酚与HCTP摩尔比、反应时间、温度对PCPZ产物收率的影响,并采用傅立叶变换红外光谱、1H和13C核磁共振、X射线衍射分析、热重分析、示差扫描量热分析对产物进行了表征。研究表明,以四氢呋喃为溶剂,采用等摩尔的氢氧化钠与苯酚,摩尔比为7.2∶1的苯酚与HCTP,反应温度65℃,反应时间48h,可得到产率为95%的PCPZ。
Phenoxy cyclotriphosphazene(PCPZ)was synthesized from phenol, hexachlorocyclotriphosphazene (HCTP) and sodium hydroxide. Effects of molar ratio of phenol to HCTP, reaction time and reaction temperature on the yield of PCPZ were investigated. Fourier transform infrared spectroscopy, 1H- NMR, 13 C- NMR, X -ray diffraction analysis, thermogravimetric analysis, differential scanning calorimetry were employed to characterize the product. Phenol and HCTP at a molar ratio of 7.2:1 were dissolved in tetrahydrofuran (THF) and reacted at 65℃ for 48 h. The yield of PCPZ was 95 %.
