| May 24, 2021 at 11:52 | comment | added | Joe Wooz | @SafdarFaisal I dissolve soap in hot water and then I transfer the cooled solution to a decancatation flask. I add concentrated HCl (37% stock solution) and then petroleum ether to increase extraction ratio. I repeat this extraction two more times (and after this I am getting 3 phases) and then I purify the organic phase twice using hot water to eliminate any HCl. I then heat the organic phase to vaporize ether and calculate TFM %. The surfactant used in the soap is sodium laureth sulfate (SLES), and I think that it may relate to why I have 3 phases but I can't tell why. | |
