应用汉森溶解度参数理论，提高了有机溶剂萃取分离低温煤焦油中非芳烃、芳烃和极性组分的选择性。通过浊度滴定法得到了溶解度参数Ra与溶解度的关系，从而可以近似比较不同溶剂与典型模型化合物（溶质）的溶解性能。根据汉森溶度球建立了改进的溶解模型，用于萃取溶剂的选择。在实践中，低温煤焦油成功地分成三部分（即，富集非芳烃、芳烃和极性组分）。实验结果表明，与椭球模型的估计具有较高的相关性。其分离产物中非芳烃、芳烃和极性组分的质量百分比均为0.001 ~ 0.001。90重量%。三种产物在总原料中的质量百分比分别约为12%、46%和36%。在整个分离过程中的质量损失为4.5%至6.0%。
The selectivity of organic solvent extraction for separating non-aromatic hydrocarbons, aromatic hydrocarbons and polar components in low-temperature coal tar was enhanced by applying the Hansen Solubility Parameters theory. The relationship between solubility parameter “distance” (Ra) and solubility was obtained by turbidimetric titration, thus allowing an approximate comparison of dissolving properties between different solvents and the typical model compound (solute). A modified dissolving model in terms of the Hansen solubility sphere was established in order to select the extraction solvent. In practice, the low-temperature coal tar was successfully divided into three parts (i.e., enriching non-aromatic hydrocarbons, aromatic hydrocarbons and polar components) by a three-step extraction-precipitation process at 298 K and 1 atm. Experimental results demonstrated a high correlation with the estimation made by the ellipsoidal model. The mass percentage of non-aromatic hydrocarbons, aromatic hydrocarbons and polar components in their separation products were all ca. 90 wt.%. The mass percentages of the three products in total feedstock were around 12%, 46% and 36%, respectively. The mass loss during the entire separation process was from 4.5% to 6.0%.
