1/10/2012, · Abstract. The distributions of, nicotinic acid, (NA) between water and trialkylamine (N235) dissolved in n -octanol was studied. The complexes of N235 and NA were investigated by Fourier transformation infrared spectrometry to deduce the reaction mechanism. It was found that N235/ n -octanol was an efficient extractant for extracting, nicotinic acid.
