为了进一步探究混合二元酸质量影响因素,结合多年二元酸生产经验与相关实验数据,重点分析了混合二元酸两种生产工艺即半连续法与连续法的优缺点,同时提出了连续法生产混合二元酸工艺的优化调整控制方法,以达到混合二元酸产品硝酸含量降低,且提高其纯度目的,进一步提升混合二元酸质量,体现出混合二元酸产品质量优势。本文还对下游客户提出混合二元酸的颜色色度的要求,提出了新的控制思路,并结合树脂反应器吸附效果的实验数据,得出了混合二元酸中催化剂含量的高低直接影响其颜色与色度,并提出了创新优化方案。

In order to further explore the factors affecting the quality of mixed dibasic acid,combined with years of dibasic acid production experience and related experimental data,this article focuses on summarizing and analyzing the advantages and disadvantages of the two production processes of mixed dibasic acid,namely the semi-continuous method and the continuous method.The optimization adjustment control method of the continuous production process of mixed dibasic acid is proposed to achieve the purpose of reducing the nitric acid content of the mixed dibasic acid product and increasing its purity,further improving the quality of the mixed dibasic acid,and reflecting the quality advantages of the mixed dibasic acid product.This article also put forward the requirements for the color and chroma of the mixed dibasic acid to downstream customers,and put forward a new control idea.Combined with the experimental data of the adsorption effect of the resin reactor,it is concluded that the content of the catalyst in the mixed dibasic acid directly affects it.Color and chromaticity,and proposed innovative optimization schemes.
