Material reaction
Thread Content
Add benzoylbenzoic acid to the toluene solvent, then add a small amount of concentrated sulfuric acid. Heat to above 105°C until reflux is achieved. Start adding methanol slowly to remove the water from the reaction medium. About 12 hours later. Dehydration is complete. Sampling control. A conversion rate of over 97% is considered acceptable. In the next step, reduce washing; a conversion rate of over 99% and a material content of less than 0.2% are considered acceptable. Evaporate the toluene. Add methanol and cool until white crystals precipitate; then centrifuge to separate the white crystals. Packaging. Please have the expert explain the process of the reaction. and effects. Only a high school education. I want to learn more. Thank you!
This is also the reaction in middle school where an acid and an alcohol combine to form an ester. -COOH+CH3-OH=-CO-OCH3+H2O.
It’s not that simple; benzoic acid dibenzoylate undergoes intramolecular dehydration and cyclization when heated in concentrated sulfuric acid, resulting in anthraquinone.
Well, the content of anthraquinones in our final product is very low, not exceeding 0.5
