Abstract

Tris(hydroxyethyl) phosphate, ethylphosphoramidic dichloride, N,N-diethylphosphoramidic dichloride, bis(hydroxyethyl) N-ethylphosphoramidate and bis(hydroxyethyl) N,N-diethylphosphoramidate were synthesized and characterized. Phosphate and phosphoramidates were polymerized with the elimination of ethylene glycol when heated under reduced pressure and they gave no molecular ion peaks in their mass spectra. And also ethylphosphoramidic dichloride gave polymeric products at 180$^{\circ}C$ with the evolution of HCl. IR spectra showed characteristic P=O streching bands in the range of 1,300 to$ 1,200 cm^{-1}.$

Tris(hydroxyethyl) phosphate, ethylphosphoramidic dichloride, N,N-diethylphosphoramidic dichloride, bis(hydroxyethyl) N-ethylphosphoramidate 나 bis(hydroxyethyl) N,N-diethylphosphoramidate를 합성하고 특성을 고찰하였다. Phosphate와 두종류의 phosphoramidate는 감압하에서 가열하면 ethylene glycol이 빠지면서 중합반응이 일어났으며 이들 화합물의 mass 스펙트라에서는 분자이온피이크를 관찰할 수 없었다. 또한 ethylphosphoramidic dichloride도 180$^{\circ}C$에서 HCl이 발생되면서 중합체로 변하였다. IR스펙트라에서는 P=O strectching의 특성밴드가 $1,300{\sim}1,200 cm^{-1}$에서 나타났다.
