Solvent-Based Extraction: The Key to Cannabis Chemistry
The large-scale key for solvent-based extraction is ethanol. Ethanol, like butane and propane, has a relatively low boiling point (173 Fahrenheit), but, contrary to the other two solvents, it requires no pressure to extract compounds from plant matter. Ethanol is also less flammable than both butane or propane, making it safer to operate for ...
