摘要
The composition of commercial reagents CYANEX(R) 923, CYANEX(R) 925, CYANEX(R) 921 and TOPO was investigated by GC/MS. CYANEX(R) 923 contains 18 components. 17 compounds were identified as trialkylphosphine oxides, mainly with normal (92.4) hexyl and octyl groups. CYANEX(R) 925 consists of 19 components. The reagent contains 65.9% of trialkyphosphine oxides, mainly with isooctyl groups. The reagent contains also trialkylphosphine sulphides, dialkyldithiophosphinic acids and dialkyldisulphides having octyl and butyl groups. Trialkylphosphine sulphides and dialkyldithiophosphinic acids are present in amount of 26.8% and can be also considered as the active substance. CYANEX(R) 921 and TOPO are high quality reagents with the content of the active substance of about 99%. Trioctylphosphine oxide is the main component.
