Decarboxylation & Terpene Boiling Points
Explore how temperature relates to primary terpenes—and why boiling, evaporation, and chemical change are different things.
Unlock the Secrets of Cannabinoids & Terpene Flavor: Dive into our Decarboxylation & Terpene Interactive Tool, where you’ll explore the fascinating world of boiling points, cannabinoid activation, effects, aroma, and flavor preservation. Discover how to enhance your sensory experience and elevate your understanding of cannabis like never before!
How to use this tool
- Pick a temperature: drag the Explore temperature slider, or press Play animation to sweep from 20°C to 280°C.
- Read each terpene bar: the dark cursor is your selected temperature and the colored marker is that terpene's boiling point. The line underneath tells you if you're below, within or above it.
- Check the Terpene Boiling Matrix: a box turns dark once your selected temperature reaches that terpene's boiling point.
- Switch units or start over: tap Show °F to change units and Reset to go back to room temperature.

Evaporation
Molecules leave a liquid surface and enter the air. This can happen well below the normal boiling point.
02
Boiling
Boiling occurs when a liquid’s vapor pressure matches the surrounding pressure. A different pressure means a different boiling point.
03
Decarboxylation
A chemical reaction releases carbon dioxide from a cannabinoid acid. THCA, for example, can convert to THC. This is a different process from terpene boiling.
Understand the science
Does decarboxylation happen at one exact temperature?
No. Temperature changes the reaction rate, while time and sample conditions affect how far conversion proceeds. Published laboratory work shows temperature-dependent reaction kinetics. A temperature reading alone cannot establish complete conversion.
Can this chart tell me how much terpene remains?
No. Retention requires measurements under defined conditions. This explorer compares temperature with published boiling references; it does not calculate loss, degradation, or product potency.
Why do different charts give different values?
Check pressure, compound identity, purity, and the original source. A reduced-pressure boiling point cannot be compared directly with a normal atmospheric boiling point. Published measurements may also differ.
