A common basic operation in the organic chemistry laboratory is the removal of a volatile organic solvent from a reaction mixture or a process such as liquidliquid extractionAlthough this operation could in principle be performed by simple distillation the fastest and most convenient method is the use of a rotary evaporator rotovap for.

A rotary evaporator or rotavap rotovap is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporationThe purpose of distillation is to separate a given mixture into its components based on their respective volatilities through the process of evaporation and condensation liquidgasliquid.
A rotary evaporator is essentially a reduced pressure distillation a solution in a round bottomed flask is placed in the water bath of the apparatus and rotated while the system is partially evacuated by a water aspirator or vacuum pump6B StepbyStep Procedures for Rotary Evaporation 5.

Apr 07 2022nbsp018332Begin rotating the flask at a medium rate by adjusting the rotation notch to roughly 110 rpm or to onethird of the maximum rotation value Figure 5Close the stopcock on the evaporator by turning it perpendicular to the bleed valve Figure 5The hissing sound should stop and the pressure inside the apparatus will decrease further.
Equitron Roteva – Rotary vacuum evaporators are efficient laboratory distillation units for applications like standard solvent distillations concentration of reaction mass or solutions separation of solvents from extracts crystallization and powder dryingAlong with carefully designed accessories it becomes a work horse in any laboratory.
Rotary Evaporation technique amp Distillation processThe distillation process is used to remove volatile solvents from liquid mixtures through vaporization and subsequent condensationIn the lab chemists and biochemists frequently use the distillation process and the rotary evaporator.
Oct 13 2008nbsp018332A rotary evaporator is used to remove large amounts of solvent from solutions at a reduced pressureThis is often done to isolate a product from a chromatographic separation or a solvent extractionAlways make yourself aware of the hazards associated with the chemicals involved in a practical before you even start.

The goal of this experiment is to isolate the natural product of eugenol from clove oilWe will do this by performing an extraction through separatory funnelsAfter shaking and burping we drain the bottom layer into a flaskWe will add the solvent being hexaneThen then they will drain the aqueous phase and we will pour the organic phase into acidic compoundsThen we will use a drying agentThen we will remove the solvent on rotary evaporator which will give us our final eugenol product.
The Rotary Evaporator It is commonly taught in General Chemistry classes that the vapor pressure of a liquid or solid varies directly with temperature ithe higher the temperature of a substance the higher its vapor pressure.
We also learned that the solution with lower density will rest on topTherefore hexane having a density of 0 rested on top of water solution having a density of 0.
We observed that Eugenol was cloudy prior to extraction because of the presence of waterWe understood water being a polar substance and eugenol being oil hence a nonpolar substance will not mix with each otherThis is what makes eugenol appear cloudy as it would happen with oil and water mixtures.
