摘要
从催化剂浓度、比例,反应压力、温度,反应停留时间,反应溶剂比,水含量及钠离子含量等方面对对苯二甲酸生产工艺中产品品质影响因素进行了探讨。通过对生产工艺进行优化调整,降低了生产成本,提高了企业在整个行业中的竞争优势。
The factors affecting the product quality in the production of terephthalic acid were discussed from the as- pects of catalyst concentration,ratio,reaction pressure,temperature,reaction residence time,ratio of reaction solvent,water content and sodium ion content.By optimizing and adjusting the prgduction process,the production cost is reduced and the competitive advantage of the enterprise in the whole industry is improved.
