Jan 22, 2019 · Ethanol is commonly removed from extraction material under reduced pressure and elevated heat in a rotary evaporator. I expected that this process would endanger the terpenes in the oil – a key component of product quality. My theory was that volatile terpenes 9 would be lost in the rotary evaporator during ethanol 10 removal.

The filtrate was concentrated on a rotary evaporator. The obtained residue was portioned between water (50 mL) and dichloromethane (50 mL). The organic phase was separated and dried over anhydrous Na 2 SO 4. Removal of the solvent gave a pale yellow solid. Yield: 1.47 g, 85%. The product was further purified by recrystallization from acetonitrile.
