Abstract
A process for extracting polyester from an article using a solvent system using a compound according to Formula I is described, where wherein R1 and R2 are each independently selected from: hydrogen, alkyl, alkenyl, alkynyl, aryl or alkoxy groups; R3 to R12 are each independently selected from: hydrogen, alkyl, alkenyl, alkynyl, aryl or alkoxy groups; and each of “a” to “e” is a carbon atom, wherein the total linear chain length of a-b-c-d-e is in the range of 2 to 5 carbons.

A process for extracting polyester from an article using a solvent system comprising a compound according to Formula I
- wherein R1 and R2 are each independently selected from:
- hydrogen, alkyl, alkenyl, alkynyl, aryl or alkoxy groups;
- R3 to R12 are each independently selected from:
- hydrogen, alkyl, alkenyl, alkynyl, aryl or alkoxy groups;
- and
- each of a to e is a carbon atom, wherein
- the total linear chain length of a-b-c-d-e is in the range of 2 to 5 carbons.
A composition comprising one or more compounds according to Formula I, for extracting polyester from an article, wherein the Formula I comprises
- wherein R1 and R2 are each independently selected from:
- hydrogen, alkyl, alkenyl, alkynyl, aryl or alkoxy groups;
- R3 to R12 are each independently selected from:
- hydrogen, alkyl, alkenyl, alkynyl, aryl or alkoxy groups;
- and
- each of a to e is a carbon atom, wherein
- the total linear chain length of a-b-c-d-e is in the range of 2 to 5 carbons.
