Separation of levulinic acid (LA) from the aqueous phase with the use of tri-n-butyl phosphate (TBP) as an extractant in nontoxic solvents such as rice bran and mustard oils was performed. The solvents are low cost and nontoxic as compared to other solvents. Separation of levulinic acid was obtained in maximum extraction efficiencies (%E) of 11.75%, 8%, and 70% in pure rice bran oil, mustard oil, and TBP, respectively. The distribution coefficient (KD) and %E were found to be lower in the vegetable oils. To improve the separation, TBP was used as an extractant with various concentrations in the mustard and rice bran oils. In the present study, higher KD and %E were obtained as 1.42 and 58.73% in rice bran oil and 1.61 and 61.75% in mustard oil.

与在无毒溶剂中稀释的磷酸三正丁酯反应分离乙酰丙酸
从与使用三-的水相乙酰丙酸（LA）的分离Ñ进行丁基磷酸酯（TBP）作为在无毒溶剂如米糠和芥末油的萃取剂。与其他溶剂相比，该溶剂成本低廉且无毒。在纯米糠油，芥末油和TBP中，乙酰丙酸的最大提取效率（％E）分别为11.75％，8％和70％。发现在植物油中分配系数（K D）和％E较低。为了改善分离效果，TBP用作芥末和米糠油中各种浓度的提取剂。在本研究中，较高的K D和％E 分别以米糠油为1.42和58.73％，芥菜油为1.61和61.75％。
