摘　　要：简要介绍了当前中国磷化工发展面临的困难和机遇。详细介绍了各种精细磷化工产品:以热法磷酸为原料的精细磷化工产品,如高聚合度聚磷酸铵、三偏磷酸钠、磷酸钾盐;以黄磷为原料生产的无机磷酸盐产品;以黄磷为原料生产有机磷产品的中间产品,如三氯化磷、三氯氧磷、五硫化二磷、五氧化二磷;以及由这些中间产品经过改变原料和工艺条件生产出的多种不同的产品,如由三氯化磷制得的三氯硫磷、亚磷酸、五氯化磷、亚磷酸酯,由三氯氧磷制得的磷酸酯、含苯的磷酸酯、磷酸三酚酯,由五硫化二磷制得的二(2-乙基己基)二硫代磷酸、硫代磷酸三苯酯、烷基二硫代磷酸。在此基础上对发展精细磷化工产品提出了建议。The present difficulties and opportunities facing the development of phosphoric industry of China were briefly introduced. Then, various fine phosphoric chemicals were introduced in detail, such as：fine phosphoric chemicals using thermal process phosphoric acid as raw material, like high - polymerised ammonium polyphosphate, sodium trimetaphosphate and potassium phosphate salt;inorganic phosphate products using yellow phosphorus as raw material;Semifinished products of organic phosphor production using yellow phosphorus as raw material,like phosphorus trichloride, phosphorus oxychloride, phosphorus pentasulfide and phosphorus pentoxide;and various different products by changing these semifinished products＇raw materials and process conditions, like thiophosphoryl chloride, orthophosphorous acid, phosphorus pentachloride and phosphite ester made from phosphorus trichloride, organic phosphate, benzene - containing organic phosphate and tritolyl phosphate made from phosphorus oxychloride, diethyldithio （ di - 2 - ethyl hexyl ） phosphoric acid, triphenyl - thiophosphate and dialkyldithio phosphoric acid made from phosphorus pentasulfide. At last, suggestions were proposed for the development of fine phosphoric chemical products.
