碳酸二苯酯和双酚A产生酯交换和缩聚反应,制得聚碳酸酯.聚碳酸酯耐压、透明性好,在机械制造、电子电器、军事及照明工业.安全与医疗器械等许多方面有着广泛的用途,是一种性能优良的工程塑料.聚碳酸酯的色泽与许多因素有关.由于原料碳酸二苯酯在制造过程中,一些沸点与之相近的杂质极易残留在产品里.要想得到高质量的聚碳酸酯,必须使其每一种杂质含量控制在100μg/g以下.至今未见报道同时检测碳酸二苯酯中3种微量杂质的分析方法.因此,本文结合单位工艺研究建立了一种用液相色谱进行分析的方法.
Polycarbonate is produced by transesterification and polycondensation of diphenyl carbonate and bisphenol A. Polycarbonate is pressure-resistant and has good transparency, and is used in many fields such as machinery manufacturing, electronics, military and lighting industries, safety and medical equipment, etc. Has a wide range of uses, is a good performance engineering plastics.Color of polycarbonate and many factors.Because the raw material of diphenyl carbonate in the manufacturing process, some similar boiling point impurities easily remain in the product. Want to get high quality polycarbonate, each of its impurities must be controlled at 100μg / g or less.To date there has been no report of simultaneous detection of three trace impurities in diphenyl carbonate analysis.Therefore, the combination of unit process to establish research A method of analysis by liquid chromatography.
