中文摘要 | 在不互溶兩相(有機相/鹼性水溶液),利用相間轉移觸媒技術進行2-丙烯酚與六氯環三偶磷氮(N₃P₃Cl[feb8])之取代反應,產物共六種(N₃P₃Cl[feb8]-[93bc](OC[feb8]H₄CH₂CHCH₂)[93bc], i=1~6),其化學位移和偶合常數與取代數成正比,利用化學位移與活化能差成正比關係可推測得活化能與取代數之關係式,此反應牽涉化學反應與質量傳送控制,文中亦求得不同取代反應之活化能,熵與焓。 |
英文摘要 | The substitution reactions of hexachlor cyclotriphosphazene, N₃P₃Cl[feb8] (I), with 2-allyphenol to synthesize the partially substituted (2-al-lylphenoxy) chlor cyclotriphosphazenes, N₃P₃Cl[feb8]-[93bc](OC[feb8]H₄CH₂CHCH₂)[93bc], i=1~6 by phase-transfer catalysis in an organic phase/alkaline solution were investigated. The reaction system was controlled by both chemical kinetics and mass transfer. The chemical shifts and coupling constants were proportional to the degree of substitution. The activation energy was predicted by the linear relationship between activation energy difference and [8ece]P chemical shift. In addition, the corresponding energies, enthalpies, and entropies of activation of the series substitution were also estimated. |
