合成了单甲基次膦酸铝(MeP-Al),并将其用作环氧树脂(EP)的阻燃剂。MeP-Al的结构通过FTIR,1 H NMR,31表征1 H NMR和XRF。使用了固化反应监测,热分析,逸出的气体和固体残留物分析,可燃性测试(LOI,UL 94),微燃烧量热仪和残留物的化学分析。20质量%的MeP-Al使EP具有所需的阻燃性和抗滴落性。该配方通过了UL 94 V0等级,LOI值为29.6%。MeP-Al主要作用于固相,少数作用于气相。MeP-Al中的P–H键可以与EP分解产生的化合物的不饱和键反应,从而在固相中形成缩合且稳定的磷酸盐。坚硬的炭是避免内部材料传热和逐渐降解的良好屏障。

An efficient synthesis of a phosphinate analogue of the anti-tumour phosphate di-ester perifosine is described (6 steps and 50% overall yield). The two phosphorus–carbon bonds in the perifosine analogue were prepared by sequential double radical hydrophosphinylation processes. This is the first example of a phosphinate analogue of perifosine, designed to be resistant to hydrolysis by phospholipid-metabolizing enzymes.

The present subject matter provides a safe alternative for producing an important intermediate useful for preparing the herbicide glufosinate, without need for chlorine components in the manufacturing process. In particular, a process for preparing alkyl phosphinic aid alkyl ester is provided, including the step of alkylating alkyl phosphinic acid ester in a non-polar solvent in the same apparatus as used to first produce the alkyl phosphinic acid ester, and without isolating the alkyl phosphinic acid ester before the alkylation step is conducted. More specifically, a process is presented for preparing methyl phosphinic acid butyl ester, by alkylating butyl phosphinic acid ester in a non-polar solvent, in the same' apparatus as used previously to first produce the butyl phosphinic acid ester and without isolating the butylphosphinic acid ester before alkylation.
