【摘要】 合成了六氯环三磷腈及其含苯氧基衍生物，通过优化实验选择了最佳反应条件，并用IR，NMR，DSC等谱学手段对合成产物进行了表征。研究发现，采用缚酸剂体系合成六氯环三磷腈的合成方法简单，反应时间短，但是反应过程中会放出大量热量，较适合小试规模的研究生产；复式催化剂／氮气体系装置较复杂，反应时间较长，但是反应过程稳定，较适于大规模工业生产。采用KOH／甲苯体系成功合成了含苯氧基的衍生物——六（苯氧基）环三磷腈、六（对氯苯氧基）环三磷腈和六（4-硝基苯氧基）环三磷腈，并利用K₂CO₃／丙酮体系改进了实验过程，发现这种体系对六（4-硝基苯氧）环三磷腈的合成非常有效。更多还原

【Abstract】 Hexachlorocyclotriphosphazene and its relative derivatives containing phenoxy group were synthesized and the best reaction conditions were selected. The products were characterized by IR, NMR and DSC. The results show that in the acid-captor system the method to synthesize hexachlorocyclotriphosphazene was simple and the reaction time was also short, but this method generally was suitable for the lab scale because of the heat given out in this system; In the duplex catalyst/nitrogen system the method was complicated and the reaction time was long, but the process was comparatively steady, so it was suitable for the industry scale. Besides that ,the derivatives containing phenoxy group were synthesized successfully by potassium hydroxide/ toluene system, such as hexakis(phenoxy)cyclotriphosphazene hexakis(p-chlorophenoxy)cyclotriphosphazenehexakis(4-nitrophenoxy)cyclotriphos-phazene. This process was also improved by the potassium carbonate/ acetone system which was found to be very effective for the synthesis of hexakis(4-nitrophenoxy)cyclotriphosphazene.更多还原
