摘要
阐述了由对二甲苯出发制备聚合用对苯二甲酸的生产工艺──氢化精制法和精密氧化法;介绍了国外相应厂家的技术经济指标;对国内今后的发展方向提出了建议。
Two pathways for manufacturing high purity terephthalic acid for the use of polymerization the hydrogenation purification and accurate oxidization were decribed. Their technical-economical indexes in the overseas corporation were introduced. The proposals for developing the technology were put forward.
