Extraction equilibria of propionic acid from aqueous solutions by Amberlite LA-2 in diluent solvents

open access: yesChemical Engineering Journal, 2009
Abstract Amberlite LA-2 (a secondary amine) was studied for its ability to extract propionic acid at different amine concentrations. The extraction of propionic acid by Amberlite LA-2 dissolved in seven single solvents (cyclohexane, 2-octanone, toluene, methyl isobutyl ketone, isooctane, haxane and 1-octanol) was investigated under various amine ...

Reactive Extraction of Levulinic Acid by Amberlite LA-2 Extractant [PDF]

open access: yesJournal of Chemical & Engineering Data, 2009
The production of organic acids at relatively low concentrations in aqueous solutions is typical of both electrochemical and biochemical syntheses. The recovery of these solute species can be achieved by solvent extraction, and the reactive recovery of carboxylic acids from aqueous solutions has received increasing attention. In this study the reactive

Comparative Equilibrium Studies for Citric Acid by Amberlite LA-2 or Tridodecylamine (TDA) [PDF]

open access: yesJournal of Chemical & Engineering Data, 2009
Carboxylic acids like citric acid are produced by fermentation. They have been used in many industrial fields as intermediate and starting materials, and their importance is still growing. It is important to separate them from the fermentation broth. In this sense, comparison of different types of solvents and amines for extraction of carboxylic acids ...

Reactive Extraction of Formic Acid by Amberlite LA-2 Extractant [PDF]

open access: yesJournal of Chemical & Engineering Data, 2008
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 ...

Extraction of Glycolic Acid from Aqueous Solutions by Amberlite LA-2 in Different Diluent Solvents

open access: yesJournal of Chemical & Engineering Data, 2009
In this work, extraction of glycolic acid was investigated from aqueous solutions by different organic solutions containing Amberlite LA-2, a secondary amine mixture. The extraction of glycolic acid with Amberlite LA-2 dissolved in six individiual solvents has been measured at 298.15 K. The solvents used were 1-octanol, cyclohexane, isooctane, toluene,

Extraction Equilibria of Succinic Acid from Aqueous Solutions by Amberlite LA-2 in Various Diluents

open access: yesJournal of Chemical & Engineering Data, 2009
The aim of this study is to investigate the extraction of succinic acid from aqueous solutions by different organic solutions containing Amberlite LA-2, a secondary amine mixture. Extraction equilibria of succinic acid in the solution of Amberlite LA-2 in seven individual diluents at a temperature of 298.15 K have been measured. Using Bizek’s approach,
