Properties and stability
Colorless to light yellow liquid. It has a powdery, sweet floral and sweet musky aroma. Insoluble in water, soluble in ethanol.
Not found in nature.
Storage method
None yet
Synthesis method
Heating tridecanedioic acid and ethylene glycol to above 200°C turns into cyclic polyester. Add the catalyst and heat to above 270°C under reduced pressure of 0.133 kPa to distill out the macrocyclic monomer.
Purpose
Its low price can harmonize with a variety of fragrances. Because of its stable properties and non-discoloration, it can be used as a fixative for a variety of cosmetic fragrances. Product quality: ester content ≥98%.
