摘要
以氯化螺环磷酸酯和酚类为原料,采用磷酰化反应生成了相应的二芳氧基季戊四醇螺环磷酸酯;通过电喷雾电离串联质谱仪(ESI MS)检测,首次提出了其质谱裂解规律,结果表明,磷酰氧键(O=P—OCH2—)和烷氧键(—OCH2—)均易断裂,为阻燃机理研究提供了依据。
Five novel spirocyclic pentaerythritol diphosphates were synthesized by phosphorylation of phenols with dichlorophosphates in this paper. The products were then characterized by electrospray ionization mass spectrometry（ ESI MS）. The fragmentation pathways were proposed for the first time, which demonstrated that the O = P-OCH2- bond and the -OCH2- bond in the phosphonate group were easy to break and provided useful information for the study of mechanism of flame retardant.
