Abstract

The use of (31)P magic angle spinning (MAS) NMR for the quantitative determination of resin loadings and the building up of oxidation products was investigated. Loadings of polystyrene-bound phosphines were evaluated via addition of triphenyl phosphate as reference compound. Results for a series of phosphines are consistent with those obtained from well-established analytical methods. The compounds were also investigated with (13)C MAS NMR, and the individual oxidation stabilities were monitored under oxygen atmosphere.

摘要

研究了使用³¹P魔角旋转核磁共振（MAS NMR）定量测定树脂负载量和氧化产物生成情况。通过添加磷酸三苯酯作为参考化合物来评估聚苯乙烯键合膦的负载量。一系列膦的结果与通过成熟分析方法获得的结果一致。还使用¹³C MAS NMR对这些化合物进行了研究，并在氧气气氛下监测了各自的氧化稳定性。
