Abstract

Oligomeric hydroxyaryloxycyclotriphosphazenes P₃N₃Cl_n(OC₆H₅)_x(OC₆H₄OH)_y are obtained by the polycondensation of phenoxychlorocyclotriphosphazenes with the general formula P₃N₃Cl_{(6 − x)}(OC₆H₅)_x (x = 3.1, 4.5) with an excess of resorcinol under homogeneous (pyridine) and heterogeneous (K₂CO₃) acceptance of HCl in a yield of 60–85%. Full substitution of the chlorine atoms in the specified oligomers (n = 0) under homogenous acceptance of HCl by pyridine is reached only at a molar ratio of phenoxychlorocyclophosphazene : resorcinol = 1 : 12; the formed oligomers contain up to 3% Cl at a ratio of 1 : 6. The structure of the compounds present in the composition of oligohydroxyaryloxycyclotriphosphazenes and their relative concentration are determined by ³¹P NMR spectroscopy and MALDI-TOF mass spectrometry.

摘要

低聚hydroxyaryloxycyclotriphosphazenes P ₃ Ñ ₃氯_Ñ（OC ₆ H ^ ₅）_X（OC ₆ H ^ ₄ OH）_ý通过phenoxychlorocyclotriphosphazenes的与通式P上的缩聚得到₃ Ñ ₃氯_{（6 -  X）}（OC ₆ H ^ ₅）_x（x  = 3.1，4.5）在均相（吡啶）和异相（K ₂ CO ₃）下存在过量的间苯二酚）接受HCl的产率为60-85％。在吡啶均一地接受HCl的情况下，仅在苯氧基氯环磷腈：间苯二酚= 1:12的摩尔比下，才能达到特定低聚物（n = 0）中氯原子的完全取代。所形成的低聚物含有最多3％的Cl（比例为1：6）。通过³¹ P NMR光谱和MALDI-TOF质谱测定低羟基芳基氧基环三磷腈组合物中存在的化合物的结构及其相对浓度。
