p-Dodecylbenzenesulfonic acid → Salicylic Acid

Participants

Reaction Steps

A mixture of 2 g of HEMA, 1.5 g of 10% p-dodecylbenzene sulfonic acid (DBSA) in heptane and 15 ml of ethyl acetate was added to the polymeric stabilizer precursor solution prepared above. The reaction mixture was stirred at room temperature overnight. The IR spectra of a dry film of the polymeric solution showed the disappearance of the azlactone carbonyl peak, indicating the completion of the reaction of the azlactone with HEMA.
