Abstract
Described herein are methods of preparing compounds derived from triglycerides or condensation polymers such as polyesters and/or polyamides. The methods may include subjecting triglyceride or condensation polymer containing matter to mechanical processing in the presence of a nucleophile.
Claims13
A method for depolymerizing polyester-containing compounds into constituent oligomer and/or monomers, the method comprising:
- contacting a polyester-containing compound with a nucleophile to form a first mixture, wherein the polyester-containing compound is a triglyceride, and the nucleophile is a hydroxide selected from potassium hydroxide, sodium hydroxide, barium hydroxide, cesium hydroxide, and calcium hydroxide;
- mechanically processing the first mixture to decompose at least a portion of the polyester-containing compound to yield a second mixture comprising the constituent oligomer and/or monomers of the polyester-containing compound;
- and
- isolating at least a portion of the constituent oligomer and/or monomers from the second mixture.
