EXTRACTION OF PALM OIL’S FREE FATTY ACIDS BY TRIETHYLAMMINE (TEA) IN POLAR-NONPOLAR MIX-SOLVENT
Indonesian Journal of Chemistry, 2010 Palm oil contains unsaturated fatty acids that can be oxidated and can make rancidity of the palm oil. One of the trigliserida degradation products is free fatty acid. The usage of triethylammine (TEA) in the polar-nonpolar mix solvents could enhance the

Solvent‐Free Photobiocatalytic Hydroxylation of Cyclohexane [PDF]
ChemCatChem, 2020 AbstractThe use of neat reaction media, that is the avoidance of additional solvents, is the simplest and the most efficient approach to follow in biocatalysis. Here, we show that unspecific peroxygenase from Agrocybe aegerita (AaeUPO) can hydroxylate the neat model substrate cyclohexane.
