Described herein are methods of preparing cutin-derived monomers, oligomers, or combinations thereof from cutin-containing plant matter. The methods can include heating the cutin-derived plant matter in a solvent at elevated temperature and pressure. In some preferred embodiments, the methods can be carried out without the use of additional acidic or basic species.

A process prepares dialkyl 1,4-cyclohexanedicarboxylates by ring hydrogenation of the corresponding dialkyl terephthalate having a CO value of less than 0.3 mg KOH/g. The dialkyl 1,4-cyclohexanedicarboxylates thus produced can be used as plasticizers or as a component of a plasticizer composition for plastics, in particular PVC.
