在等温条件下，研究了Amberlite LA-2在五种不同酯（邻苯二甲酸二甲酯、己二酸二甲酯、琥珀酸二甲酯、戊二酸二甲酯、碳酸二乙酯）、五种不同醇（异戊醇、己己醇、辛烷醇、壬烷醇、癸烷醇）和两种不同酮（二异丁基酮（DIBK）、甲基异丁基酮（MIBK））作为稀释剂对甲酸的萃取以及纯稀释剂的萃取能力。所有的测量都是在298.15 K下进行的。对物理萃取法和反应萃取法进行了比较。计算了负载系数TT、萃取效率E、改良分离系数SF和分配系数KD。发现异戊醇是最有效的溶剂，最大分布值为19.223。建立了线性溶剂化能关系（LSER）模型方程，计算出醇类的分布系数，R平方为0.976。
The reactive extraction of formic acid by Amberlite LA-2 dissolved in five different esters (dimethyl phthalate, dimethyl adipate, dimethyl succinate, dimethyl glutarate, diethyl carbonate), five different alcohols (isoamyl alcohol, hexan-1-ol, octan-1-ol, nonan-1-ol, decan-1-ol), and two different ketones (diisobutyl ketone (DIBK), methylisobutyl ketone (MIBK)) as diluents as well as the extraction capacity of pure diluent alone have been studied at isothermal conditions. All measurements have been carried out at 298.15 K. The comparison of physical and reactive extractions has been studied. The loading factor, TT, extraction efficiency, E, modified separation factor, SF, and distribution coefficients, KD, have been calculated. The isoamylalcohol has been found to be the most effective solvent with a maximum distribution value of 19.223. Furthermore, the linear solvation energy relationship (LSER) model equation has been obtained to calculate distribution coefficients for alcohols with an R square of 0.976.
