摘要
浅析PTA产品光学质量的不同指标的含义和形成机理 ,同时阐述实际生产中PTA产品光学质量的影响因素。指出在满足PX质量要求的前提下 ,通过在氧化反应过程中加强对粗TA光学密度的控制 ,可保证PTA产品的b 值 。
Several crucial features of PTA optical quality and the mechanism of the features were introduced.The process factors related to the features were analyzed.The conclusion was drawn that PTA b -value can be controlled to satisfy the requirement of the customers by means of adjusting the optical density of crude terephthalic acid in the oxidation process.
