Abstract:The synthesis of tri(n-butyl)phosphine in THF was introduced and synthetic conditions were optimilized. When THF was solvent, n(Mg)∶n(C_4H_9Br)∶n(PCl_3)is 1.05∶1.0∶0.27, temperature of Grignard reagent's synthesis is in reflux, temperature of alkylation is -3~0 ℃, reaction time is 1~2.0 h , yield of tri(n-butyl)phosphine in n-butyl bromide is 53.1%. The product was analyzed by RI,~(1)H-NMR,~(31)P-NMR and GC. |
Key words:tri(n-butyl)phosphine; THF; n-butyl bromide; synthesis |
