                        Triphenylphosphine (Ph3P, TPP) is one of the most important in the three aryl phosphonic and refinement for Bai Sejing form solid, is widely used in organic synthesis, is contemporary oil chemical industry, fine chemical production of homogeneous catalysts used in important ligands, such as Wilkinson catalysts for olefin homogeneous catalysis hydrogenation and d antimony and reagents used in fine chemical industry, etc., and continuously expand new USES, demand is increasing year by year.

                         The falklands method is adopted to benzene, phosphorus trichloride, sulfur directly reflux reaction, generate sulfur triphenyl phosphine, then through zinc powder reduction was triphenylphosphine. Which USES the sulfur triphenyl phosphine was isolated and using zinc powder as new technology such as reducing agent. The method has high yield, pure product and moderate reaction conditions, etc.

                       Xiang ying analysis technology co., LTD., the newly developed XiangyingGC7990plus capillary gas chromatographic determination of triphenylphosphine (Pph3) purity test method of 10 m x 0.53 mm x 2.65 mu m quartz capillary column separation, using normalization method of quantitative. Pph3 RSD0.014 % purity analysis data; Single sample analysis time 9 min. The method is simple, rapid, precise, accurate result, apply to Pph3 purity analysis of the quality control.

                            三苯基膦(Ph3P ,TPP)是三芳基膦中***重要的一种 ,纯品为白色晶形固体 ,广泛应用于有机合成中 ,是当代石油化工 ,精细化工生产中所用均相催化剂的重要配体 ,如烯烃均相催化加氢的威金森催化剂以及用于精细化工的维锑希试剂等 ,且新用途不断开拓 ,需求量逐年增加。
                          采用弗 克法 ,以苯 ,三氯化磷 ,硫磺直接回流反应 ,生成三苯基硫膦 ,再经锌粉还原制得三苯基膦。其中采用不分离出三苯基硫膦以及用锌粉作还原剂等新工艺。该法具有收率高 ,产品纯 ,反应条件缓和等特点。
                        滕州市翔鹰分析技术有限公司新开发的XiangyingGC7990plus毛细管气相色谱测定三苯基膦(Pph3)纯度的试验方法10m×0.53mm×2.65μm石英毛细管柱分离,采用归一化法定量。Pph3纯度分析数据RSD0.014%;样品单次分析时间9min.方法操作简单、快速,结果精密、准确,适用于Pph3纯度的质控分析。
