Abstract Extraction of hydroxylation solution by tributyl phosphate in 4-methyl-2-pentanone was studied.The phase equilibrium data,equilibrium distribution coefficient and the extraction percentage were tested.The compositions of complexes were determined by the hyperbolic logarithm method.The experimant shows that the extraction percentage can reach 99.76% when tributyl phosphate is used and it is prior to traditional solvent extraction.
