Extraction of Propionic Acid from Aqueous Solution Using Tributyl Phosphate IN Modified Soyabean Oil

The experimental studies for extraction of propionic acid using Tributyl Phosphate (TBP) in nontoxic diluent (modified soyabean oil) from aqueous solution have been described here. The extraction equilibrium studies for propionic acid are carried out to find the optimum time of shaking, the effect of temperature and the extraction efficiency (%E). The experimental studies show that extractant (TBP) and diluent influences the extraction of propionic acid. The effect of percentage of TBP in diluent on extraction efficiency has been investigated.
