In this study, gallic acid was separated by triphenylphosphine oxide in
the presence of conventional solvents. Triphenylphosphine oxide is an
organophosphorus extractant and highly selective towards carboxylic
acids. Reactive extraction results were compared with physical
extraction results. The extraction efficiencies reached up to 61, 76,
86, 67, and 84 % in the presence of triphenylphosphine oxide with oleyl
alcohol, dimethyl adipate, isobutanol, methyl isopropyl ketone, and
methyl ethyl ketone, respectively. Further, the number of theoretical
units and the solvent to feed ratio were calculated for the practical
design of a liquid-liquid extraction column. Roughly 2 to 4 theoretical
units were calculated to meet the targeted extraction efficiencies.
Gradient boosting algorithm showed a good performance to predict the
results. This study is the first to investigate the reactive extraction
of gallic acid by triphenylphosphine oxide, and include fundamental
information for the recovery of gallic acid.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
