Abstract

The extraction of water-soluble total alkylresorcinols from the tar water of the Kiviter shale-chemical process with methyl isobutyl ketone was studied. The effects of the volume ratio between contacting phases, the time and rate of mixing, the temperature regime, and the initial concentration of total phenols on the degree of their extraction were considered. A maximum recovery of 99% was obtained. The advantages of methyl isobutyl ketone (MIBK) over butyl acetate (BA), which is used in the operating production process, were shown.

甲基异丁基酮从基维特法焦油水中提取水溶性总烷基间苯二酚

摘要

研究了甲基异丁基酮从Kivite页岩化工过程焦油水中提取水溶性总烷基间苯二酚。考虑了接触相之间的体积比、混合时间和速率、温度范围和总酚的初始浓度对其提取程度的影响。获得了 99% 的最大回收率。显示了甲基异丁基酮 (MIBK) 相对于生产过程中使用的乙酸丁酯 (BA) 的优势。
