In this video I synthesize o-aminobenzoic acid (anthranilic acid) by oxidation of phthalimide with sodium hypochlorite solution. The protocol I used came from prepchem.com although I modified it based on suggestions given by ChemPlayer on their BitChute video where they carry out the same reaction but using a different synthesis protocol. I try to do all my own work but after attempting this synthesis once and having it crash and burn I decided to consult the masters of home chemistry. There is no shame in accepting help from the great chemists who have come before us.
The prepchem protocol had an additional feature that I didn't see anywhere else where anthranilic acid that would have been lost in the filtrate was recovered as cupric anthranilate which is then reacted with H2S gas to produce copper(II) sulfide and free anthranilic acid in solution. Although I did not do the reaction with the hydrogen sulfide gas I did recover the anthranilic acid from the filtrate as cupric anthranilate in order to calculate a yield for the synthesis. That cupric anthranilate can be stored for conversion to free anthranilic acid later or it can be used as is in other experiments.
