Synergistic effect of some alcohols on the extraction of H3PO4 from Syrian wet phosphoric acid by TBP

Abstract

This paper studies the synergistic effect of some alcohols such as isoamyl alcohol, pentanol, hexanol and heptanol on the Extraction of H3PO4 from Syrian phosphoric acid by (TBP). The possibility to use these alcoholic compounds as a diluent instead of kerosene was also studied. The results show that the alcohols have higher extraction yeild than (TBP) diluted in kerosene. The alcohols have an important synergistic effect, when they were used asdiluent instead of kerosene, on the Extraction of H3PO4 by (TBP) and they have a higher extraction yeild and a quicker phase separation compared with kerosene. Extraction of uranium, fluoride, sulfate and heavy metals by these reagents is relatively small. © Periodica Polytechnica 2007.
