| Abstract: | Partition characteristics of pyrogallol in propanol - ammonium sulfate aqueous two - phase system was studied, and the formation of aqueous two - phase and the effect of ammonium sulfate amount, propanol volume fraction, solvent amount and pH on partition ratio was investigated. The optimum extraction condition was determined as follows ： am- monium sulfate amount as 6 g, propanol volume fraction as 60%, ratio of raw materials and solution as 1 ： 20 in pH 5.57, with the maximum partition ratio of 5.5 and the extraction rate of 79%. |
