To determine the solubility of benzoic acid, 4-chlorobenzoic acid and 2-phenylbutyric acid in TFE with the SAMS HNMR method.
14:40 - Added each solid to a 1 dram screw cap vial. Each vial was filled roughly 1/3-1/2 of its total volume.
14:43 - Added a few drops of TFE to each solute. Samples 1 and 2 dissolved only slightly, added about 0.5 mL TFE to each.
14:45 - Added all three samples to a 45C bath.
14:53 - 3 Is now a clear solution, moved each sample to a 25C bath.
15:20 - Filtered each solution using a kimwipe stuffed inside a pipette.
15:37 - Added CDCl3 to each supernatant. Sample #1 instantly became cloudy. After settling, the sample formed layers.
15:38 - Transferred samples 2 and 3 to NMR tube.
15:57 - Took HNMR of samples 2 and 3 using 500MHz varian NMR.
