乙酸甲酯是PTA生产中主要的副产物之一,通过分析乙酸甲酯在氧化反应器中的行为,得出乙酸甲酯利用可以降低乙酸的单耗,并提出乙酸甲酯综合利用的几种方式:回收的乙酸甲酯循环到氧化反应器内;回收的乙酸甲酯水解成乙酸。
Methyl acetate is one of the major byproducts in the production of PTA. By analyzing the behavior of methyl acetate in the oxidation reactor, it can be concluded that the use of methyl acetate can reduce the consumption of acetic acid and propose several kinds of comprehensive utilization of methyl acetate Mode: The recovered methyl acetate is recycled to the oxidation reactor; the recovered methyl acetate is hydrolyzed to acetic acid.
