Abstract
This study investigates the use of vegetable oils as sustainable diluents in the reactive extraction of tartaric acid (TA) using trioctylamine (TOA). Their performance was compared with 1-octanol as a reference solvent. All oils showed comparable efficiencies, with canola oil (CNO) performing slightly better. Extraction was strongly affected by pH, temperature, and concentrations. The highest efficiency was obtained at the natural pH (1.42), whereas higher temperatures and TA concentrations reduced performance. Increasing TOA concentration improved extraction. Under optimal conditions (0.2 M TA, 1.0 M TOA, and 298.15 K), efficiencies reached 91% (distribution coefficient, KD = 10.11) for CNO and 97.2% (KD = 35.1) for 1-octanol. More than 99% of TA was recovered from the loaded organic phase, and the organic phase was reused with minimal loss. These results demonstrate that vegetable oils are promising green alternatives for TA extraction.
本研究探讨了植物油作为持续稀释剂在三辛基胺反应萃取酒石酸（TA）中的应用。并与1-辛醇作为标准溶剂进行了性能比较。所有的油都显示出相当的效率，菜籽油（CNO）的表现略好。提取受pH、温度和浓度的强烈影响。在自然pH值为1.42时效率最高，而较高的温度和TA浓度会降低效率。增加TOA浓度可改善萃取。在最佳条件（0.2 M TA, 1.0 M TOA, 298.15 K）下，CNO的效率达到91%（分配系数KD = 10.11）， 1-辛醇的效率达到97.2% （KD = 35.1）。从负载的有机相中回收了99%以上的TA，并且有机相以最小的损失重复使用。这些结果表明，植物油是有前途的绿色替代TA提取。
