Extraction of Ruthenium(III) from Hydrochloric Acid Solutions by High Molecular-Weight Quaternary Ammonium Compound.

Extraction of Alumina from Local Clays by Hydrochloric Acid Process

A bench work study was carried out to investigate the use of kaolinitic clay containing 29.4% Al2O3 extremely abundant in Saudi Arabia for the production of pure alumina by calcination at 700 o C for 1h (recommended by previous investigators) then leached by hydrochloric acid. The effects of leaching temperature (25 o C to boiling temperature), period of activation (10-150 minutes), acid concen...

Extraction of gallium(III) from hydrochloric acid solutions by trioctylammonium-based mixed ionic liquids.

The extractabilities of aluminium(III), gallium(III), and indium(III) from hydrochloric acid solutions were investigated using a mixture of two protic ionic liquids, trioctylammonium bis(trifluoromethanesulfonyl)amide ([TOAH][NTf(2)]) and trioctylammonium nitrate ([TOAH][NO(3)]). At a HCl concentration of 4 mol L(-1) or more, gallium(III) was nearly quantitatively extracted and the extractabil...

Extraction of Gold(iii) with Mbimtt from Hydrochloric Acid

Separation of Formic Acid from Aqueous Solutions by Liquid Extraction Technique at Different Temperatures

In this study, the separation of formic acid from aqueous solutions was investigated. Liquid-liquid equilibrium (LLE) data including tie-lines was reported for water + formic acid + 2-methylpropyl ethanoate ternary mixture at (293.15 to 323.15) K and atmospheric pressure. The system shows type-I phase behavior based on Treybal’s classification because only one partially miscible binary mixture ...
