Low-temperature coal tar (LTCT) is a sticky liquid mixture produced mainly from coal pyrolysis, which contains various value-added chemicals (VACs). Liquid-liquid extraction is considered as one of the green and effective ways to explore the organic composition and separate the VACs from LTCT. Herein, petroleum ether, methanol, and carbon disulfide were used to extract arenols from a LTCT. As a result, the relative content and absolute content of arenols extracted from the LTCT are ca . 96.3% and 85.9%, respectively. Among them, p -cresol is predominant, accounting for 22.2%. The isolated contents of arenols are up to 84.6%. Moreover, a kilogram-scale operation was carried out under the same conditions, which offers a potential application in industrial production.

液-液萃取分离低温煤焦油中的壬醇

低温煤焦油 (LTCT) 是一种主要由煤热解产生的粘性液体混合物，其中包含各种增值化学品 (VAC)。液-液萃取被认为是探索有机成分和分离 VAC 与 LTCT 的绿色有效方法之一。在本文中，石油醚、甲醇和二硫化碳用于从 LTCT 中提取壬醇。因此，从 LTCT 中提取的壬醇的相对含量和绝对含量约为 . 分别为 96.3% 和 85.9%。其中以对甲酚为主，占22.2%。分离出的壬醇含量高达84.6%。此外，在相同条件下进行公斤级操作，这为工业生产提供了潜在的应用。
