<prompt> Ukuhlanganiswa kwe-aspirin kuhlukaniswa njengendlela yokusabela kwe-esterification. I-salicylic acid iphathwa nge-acetic anhydride, i-acid derivative, edala ukusabela kwamakhemikhali okuguqula iqembu le-hydroxyl le-salicylic acid libe yiqembu le-ester R-OH R-OCOCH3. Le nqubo ikhiqiza i-aspirin ne-acetic acid, okubhekwa njengomkhiqizo ohlangothini walesi ukusabela. Amanani amancane e-sulfuric acid futhi ngezikhathi ezithile i-phosphoric acid cishe ahlala esetshenziswa njengento yokuvuselela. Le ndlela ivame ukusetshenziswa kumalabhorethri okufundisa ama-undergraduate. Umbuzo: Isetshenziselwani i-sulfuric acid?  <response>: isishukumisi
