I'm trying to work on a separation scheme for 50% 1,2,4,5-tetrachlorobenzene, 40% o-toulic acid, and 10% 1,4-dibromobenzene. I could really use your advice ASAP, thank you! Using crystalllization and acid-base extraction, I need to sperate and purify at least 2 of the 3 compounds listed. The following reagents are available: 1M NaOH, 6M NaOH, 1M HCl, 6M HCl, 1M NaHCO3, saturated sodium chloride, diethyl ether, 95% ethanol, methanol, isopropyl alcohol, actone, hexane, toulene, methylene choride, and granular anhydrous sodium sulfate.
