Abstract:
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.
Abstract:
The invention relates to an ionic liquid composition and a method for preparing the ionic liquid. The ionic liquid comprises a cation containing the Formula I , disclosed, and wherein: n is 1 or 2, R 1 is selected from the group consisting of: H, C 1 - C 12 alkyl, aryl or together with R 2 may form a heterocyclic ring, and R 2 is selected from the group consisting of: H, C 1 - C 12 alkyl, aryl or together with R 1 may form a heterocyclic ring, and R 3 is selected from the group consisting of hydrogen and C 1 -C 12 alkyl, wherein if n is 1, then R 3 is C 1 -C 12 alkyl; and wherein R 1 and R 2 are not simultaneously selected from hydrogen. The method for the preparation of the ionic liquid composition provided herein starts with at least one N-substitution of the compound of Formula II , as herein disclosed, and wherein: n is 1 or 2, R 3 is selected from the group consisting of hydrogen and C 1 -C 12 alkyl, wherein if n is 1, then R 3 is C 1 -C 12 alkyl. Further provided is a use of the ionic liquid in a chemical method including at least a method for electro-chemical oxidation.
