摘　　要：以自制双（4-甲苯基）苯基硫化膦（BMPPS）粗品为原料,经多次重结晶提纯后,用薄层色谱（TLC）、高效液相色谱（HPLC）进行分析,纯品BMPPS的纯度为99.2%,可用作定量分析对照品。对纯品UV扫描发现,BMPPS的吡啶溶液在303nm处有稳定吸收,在浓度为8×10^-4~4×10^-3mol/L范围内吸光度与浓度呈良好的线性关系,回归方程为：y=190.6x＋0.377,r=0.9978。加标回收率为98.5%~103.8%,方法重现性良好,可用作合成BMPPS粗品的定量分析。The control sample of bis （4-methylpbenyl） phenyl phosphine sulfide （BMPPS） was obtained by recrystallization of a serf-prepared crude starting material. And the purity of BMPPS, which was measured with thin-layer chromatography and high pressure liquid chromatographic analysis, was 99.2 %. The ultraviolet-visible spectruphotometric scanning showed that the solution of BMPPS in pyridine revealed a maximum stable absorption at 303 nm. And the concentration of BMPPS was correlated very well to its optical density in the range of 8×10^-4mol/L-4×10^-3mol/L mol/L.The regression equation is y = 190.6x ＋ 0.377 with a relativity coefficient of 0. 998 7. When the method was used to analyze the crude BMPPS, recovery of control is 98.5% - 103.8% with a better repeatability. Ultraviolet spectruphometric method is a feasible instrument, for quantitative analysis of crude BMPPS.
