摘要

本文报道[2

苯基膦酸二苯酯（d

-DPPP）的制备及其γ辐解。采用气相色谱-微波等离子体发射光谱（GC-MPES）测定d

-DPPP辐解低沸产物的氘含量（D%）及氘碳比（D/C）

依此估算出C—P及C—O键的断键几率。低温（77 K）及常温γ辐照后DPPP的顺磁共振谱与三苯基磷酸酯及苯基膦酸γ辐照后的ESR谱图极相似，都是三重的三线峰。同时亦对DPPP、d

-DPPP及其它一些芳基磷（膦）酸酯的质谱图作了比较，并讨论它们在质谱条件下的断键规律。

Abstract

The present paper reports the synthesis and gamma-radiolysis of diphenyl 2

6-D

-phenylphosphonate

The deuterium concentration D% of the radiation products was determined by GC-MPES method

the probability of bondbreaking of C—P bond was 0.013

and of O—C bond was 0.987. The ESR spectra measured after γ-irradiation of DPPP samples at ambient temperature dominated by that for cyclohexadienyl-type radicals

while the spectra of low-temperature (77 K)irradiated DPPP were characteristic of phenyl radicals. The MS spectra of DPPP and d

-DPPP were measured and compared.
