包含酚和钠硫酸盐的高集中的废水在癸二酸酸(SA ) 被产生工业。北河二双子座油酸，为生产 SA 的原料，能被用来从废水提取酚以便减少在酚的过程和分泌物使用的酚的数量。抽取机制是酚的那个氢氧根组的结果表演被氢债券连接到海狸油酸的 carboxyl 组。在 30 min 的抽取过程途径平衡。抽取比率随钠硫酸盐和海狸油酸的增加增加，并且作为酚增加减少。当油水比率是 1 时：3， 40 的最佳的分发系数被获得。在海狸油酸的酚浸透集中是 1.03 摩尔潬敶吗？

英文摘要：

Wastewater containing high concentrations of phenol and sodium sulfate is generated in sebacic acid （SA） industry. Castor oil acid, a raw material for producing SA, can be used to extract phenol from wastewater in order to reduce the amount of phenol used in the process and discharge of phenol. The results show that the extrac- tion mechanism is that hydroxyl group of phenol is linked to carboxyl group of castor oil acid by hydrogen bond. The extraction process approaches equilibrium in 30 min. Extraction ratio increases with the increase of sodium sulfate and castor oil acid, and decreases as phenol increases. When the oil-water ratio is 1 ： 3, the optimal distribu- tion coefficient of 40 is obtained. Phenol saturation concentration in castor oil acid is 1.03 mol.L-1 after extraction for 4 times. The equilibrium constant （Kex） at 25℃ is 8.41 and the endothermic enthalpy （AH） is 1.513 kJ.mo1-1. The Gibbs free energy （AG） is -5.277 kJ. tool-1 and the value of AS is calculated to be 22.3 J. mo1-1. K-1.
