IONIC LIQUID SOLVENTS AND A PROCESS FOR THE DEPOLYMERIZATION OF POLYAMIDES
摘要
An improved process for the hydrolysis of nylon polymer is herein disclosed using ionic liquids and optionally one equivalent of sulfuric acid per amide residue of the polymer. The process provides for a simplified means for separation of the hydrolyzed polyamide constituent monomers.
