摘要
对十几年来黄磷净化与高纯磷制备技术的进展进行了评述，对相应的技术开发工作提出了新的见解和建议。黄磷精馏法和磷化氢法，只要对原料黄磷采用适当的预处理措施，所得精制磷可以达到很高的纯度。对于特定的应用，要根据对某种或某些杂质的特定要求选择适当的净化方法。
The technical progress in purifying yellow phosphorus and preparing highpurity phosphorus for over ten years are reviewed.The suggestions of the technical development are also given.Using the rectification or the phosphine pyrolysis method,the purity of refined phosphorus could be very high if only the proper pretreatment is carried out for yellow phosphorus.For the special application,a proper method should be selected for the purifying yellow phosphorus according to the special requirement of some impurities.
