Terpenes evaporate at temperatures typically below 100°C.
Each terpene has its own specific boiling point.
In cannabis oil distillation, terpenes are separated using short path distillation under vacuum conditions.
This method reduces the required temperatures for evaporation.
4 Key Factors You Need to Know About Terpene Evaporation
1. Boiling Points of Terpenes
Terpenes are aromatic compounds found in cannabis and other plants.
They have lower boiling points compared to cannabinoids like THC and CBD.
For example, THC begins to evaporate at 157°C and CBD at 160 to 180°C.
Terpenes typically evaporate at temperatures below 100°C.
This difference in boiling points is crucial for their separation during distillation processes.
2. Short Path Distillation
This method is used to separate terpenes from cannabis crude oil.
It involves heating the oil under controlled vacuum conditions.
The vacuum reduces the atmospheric pressure, allowing the terpenes to evaporate at lower temperatures.
Higher temperatures can degrade the terpenes, affecting their aroma and therapeutic properties.
3. Evaporation Under Vacuum
In short path distillation, the vacuum level is adjusted to a range of 0.001 to 1 mbar.
This adjustment ensures that terpenes evaporate selectively without reaching the higher temperatures needed for cannabinoids.
The evaporated terpenes are then collected through condensation, preserving their integrity.
4. Importance of Temperature Control
At about 100°C, volatiles including some water evaporate.
This is significant for terpenes as they are volatile and sensitive to heat.
Maintaining temperatures below their degradation points is essential to retain their beneficial properties.
Preservation of Terpenes
The text emphasizes the fragility of terpenes and the need for careful temperature control during distillation.
By selectively pulling terpenes at the right temperatures, they can be preserved for later use in various products.
This enhances the flavor and therapeutic effects of cannabis extracts.
In summary, terpenes evaporate at temperatures generally below 100°C.
Precise boiling points depend on the specific terpene.
The use of short path distillation under vacuum conditions allows for the efficient and selective evaporation of terpenes at lower temperatures.
This ensures their preservation and quality.
