| Abstract: | The individual and selective extraction of acetophenone and methylbenzylamine with n-heptane without and with 1-octanol has been analysed at different pH values, using an extraction system that avoids the reciprocal dispersion of the two phases. For individual extraction, the values of acetophenone mass flow were for 1.6–2.1 times higher than that of methylbenzylamine. The interfacial transfer has been accelerated by adding 1-octanol into the organic phase. The difference between the interfacial mass transfer rates of acetophenone and methylbenzylamine has been amplified during the separation of these compounds from their mixture. In the presence of 1-octanol the selectivity factor reached values over 1,000. |
