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 Evaporator Ethanol Extraction - Coldfinger .

Oct 11, 2019 · Rotary evaporators allow many configurations depending on the use. A diagonal glass condenser is common for standard distillation of non-volatile substances. Vertical class condensers allow solvents with higher boiling points. For ethanol extraction with dry ice, a rotary evaporator with a cold finger glass condenser is ideal.

Vacuum distillation - Wikipedia

Vacuum distillation is distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique separates compounds based on differences in boiling points. This technique is used when the boiling point of the desired compound is difficult to achieve or will cause the compound to decompose.

TSPS Engineering Manual

In a flash type evaporator, heated salt water passes through an orifice into an area of lower pressure which is created by an air ejector or vacuum pump. A portion of the water flashes into steam, and the steam passes up to a vapor separator, where water droplets are removed, and then to a distilling condenser where the vapor is condensed.

If your institution uses a water circulator connected to the condenser to minimize water usage (open cabinet of Figure 5.65), be sure that there is ice in the water reservoir.

Information

Rotary evaporation can separate solvent from different types of mixtures and materials but it is crucial that the desired compound has a higher boiling point than the solvent. Lower boiling point solvents work best, but rotary evaporation is more commonly used to remove water (b.p. 100 ˚C).
