Preparation of Novel Functionalized Ammonium Salts that Effectively Catalyze Depolymerization of Nylon-6 in Ionic Liquids
A new type of ammonium salt containing DMAP in the cation was prepared and applied for the depolymerization of nylon-6 giving monomeric caprolactam in high yield through direct distillation. The ionic liquids could be used at least five times.
