what's with the selinene from celery extract that makes it an organic alternative to CFCs as coolant?

Question

selinene comes from celery root extract.

Answer 1

"Selinene, an Organic Alternative to CFC’s as Coolant or Refrigerant," probed the possibility of using an organic celery extract as a replacement for ozone depleting chlorofluorocarbons, or CFCs. Selinene, which is a chemical compound present in celery oil, has energy absorption properties that are similar to CFCs, without the harmful side effects.
