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.

Mechanical rotation of a magnetic stirrer or a rotary evaporator can induce an enantiomeric excess of supramolecular species. In this study, we investigate the effect of fluid motion in a rotary evaporator on chiral supramolecular species. It is shown theoretically that the twisting effect of fluid motion on cylindrical particles is expressed in terms of helicity dissipation rate.

Evaporator - an overview | ScienceDirect Topics

The Rotary evaporator is a common laboratory apparatus used for quick removal of solvents from reaction mixtures. This is done by heating mixtures gently under reduced pressures to accelerate the rate of evaporation. A vacuum evaporator used to work by bringing down the pressure over a mass of fluid, thus reducing the boiling points.

Rotary Evaporation to Remove Solvent | Protocol

Rotary evaporation is a technique commonly used in organic chemistry to remove a volatile solvent from a non-volatile compound of interest. Invented by Lyman C. Craig in 1950 the rotary evaporator, or rotovap, gently removes solvents from compounds using heat combined with reduced pressure to evaporate, dry, and purify samples for further downstream use.

Rotary evaporation is the process of reducing the volume of a solvent by distributing it as a thin film across the interior of a vessel at elevated temperature and reduced pressure. This promotes the rapid removal of excess solvent from less volatile samples. Most rotary evaporators have four major components: heat bath, rotor, condenser, and .

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.
