Just finished reflux. 25 mL of isopropyl alcohol, 7.3 grams of salicylic acid, and 0.5 mL of sulfuric acid, refluxed for 1.5 hours. I poured it all
into a beaker to evaporate off some isopropyl alcohol, and isopropyl alcohol is so strong smelling that it overpowers any ester smell. Maybe i can
detect some greenish odor but not sure. No color change or gasoline smell. I'm a bit concerned that I didn't use enough sulfuric acid for catalysis.
now i'm waiting for evaporation, in a day or 2 I hope a layer forms. if not I will try again with more sulfuric acid
Do u guys think that was enough sulfuric acid? it's the same molar ratio that nurdrage used for ethyl propionate
