Equilibrium Study on Reactive Extraction of Acetic Acid with Tri-n-butyl Phosphate in N-hexane
Extraction of carboxylic acids from dilute aqueous solution using traditional solvents such as ketones, alcohols, ethers, and ester is inefficient because the distribution ratio is rather low. Reactive extraction which exploits reversible chemical complexation is an effective separation process for extraction of carboxylic acids from aqueous streams such as fermentation broths and wastewaters. ...
متن کاملReactive Extraction of Propionic Acid Using Tri-N-butyl Phosphate in Petroleum Ether: Equilibrium Study
In present paper, the recovery of propionic acid from aqueous phase by reactive extraction was studied using tri-n-butyl phosphate (TBP) in petroleum ether. Extraction using pure diluent was found to be poor. Using the mixture of extractant-diluent the extraction was significantly improved. Results were presented in terms of distribution coefficient, equilibrium complexation constant, loading r...
متن کاملIntensification of Propionic Acid Separation from Aqueous Solution using Reactive Extraction with Tri-n-butyl Phosphate (TBP) Dissolved in n-Decane and 1-Decanol
Over the last three decades, there has been a resurgence of interest in large-scale production of fermentation chemicals due to the sharp increase in petroleum cost. So the potential role of a new energy efficient fermentation technology is receiving growing attention. Propionic acid is widely used in the food, pharmaceutical and chemical industries. Fermentation technology for the production o...
متن کاملStudying the Photocatalytic Degradation of Tri-n-Butyl Phosphate Using Nano Nd-Doped TiO2
Photocatalytic method was used as an efficient and simple way for degradation of tri-n-butyl phosphate (TBP). In contrast to other methods, in this method the mineralization occurs and no twin pollution is generated. Nd doped TiO2 was synthesized via sol gel process and characterized by XRD and TEM tecniuqes. Then it was used as photocatalyst for TBP degradetion. It was found that the solution ...
متن کاملIntermolecular structure in tri-n-butyl phosphate/n-octane mixtures: a molecular dynamics simulation study
Tri-n-butyl phosphate (TBP) is an important extractant for heavy metal ions. The microscopic structure of TBP/n-octane mixtures as a function of concentration of TBP is examined through atomistic molecular dynamics simulations. A weak association between TBP molecules both in pure TBP as well as in the octane solution is established. In dilute TBP/n-octane solutions, TBP molecules are inhomogen...
