Rotovap In Organic Chemistry

Apr 07, 2015 A rotovap typically uses a cold condenser to condense the solvent into a collection flask. But the distillation is typically done under weak vacuum as well. So the solvent sitting in the collection flask seem susceptible to re-vaporizing and getting sucked into the vacuum pump.

Dec 05, 2017 -Once all solvent has been pushed into the collection base, bleed off the nitrogen pressure. Once both vessels have reached 0 psi, you can attach rotovap injection valve to the 1/4 dedicated liquid dip tube valve on the collection base. Begin a rotovap procedure to recover your ethanol.

Drying Methods. Aqueous Wash with Brine: The final brine wash during workup is extremely effective for removing most of the water from the organic layer. The rest of the water can be removed using one of the drying agents listed below. Magnesium sulfate: Fast, always works, but kind of messy. Sodium Sulfate: convenient for small scale drying ...

In a Graham-type condenser (the right condenser in the picture below), the water flows around a tube (whether straight or coiled) that contains the vapor/condensed liquid. ( picture source) The Graham-type condensers clog (or flood) more easily since they have a more restricted path for the liquid to return to the pot.

In organic chemistry, we will learn about the reactions chemists use to synthesize crazy carbon based structures, as well as the analytical methods to characterize them. We will also think about how those reactions are occurring on a molecular level with reaction mechanisms. Simply put, organic chemistry is like building with molecular Legos.

Jul 21, 2017 The rotovap size depends on how many liters you need to recover. That being said, the most common sizes are 5L, 10L, 20L, and 50L. The size refers to the size of the evaporating flask. It’s important to note that the flask is not loaded at max capacity during operation, but usually around 20-40% capacity. ...

Mar 05, 2020 A Rotovap is an important apparatus that is widely used for solvent removal through a method known as rotary evaporation. The technique is most common in organic chemistry, but also makes life simple in reality through a number of industrial applications. The apparatus has to be used with greater care while following the safety instructions to ...

Oct 03, 2019 After separation and washing, the non-polar organic phase remains as a hydrochloride solved in dichloromethane. Since we do not have access to a rotovap, I wonder how it could be concentrated? Someone suggested simply magnetic stirring (evaporation of DCM over time) which should leave the crude hydrochloride salt.

Oct 10, 2013 A rotavap is really for organic synthesis. After working up your reaction 90% of the time your desired product is in an organic solvent of some description (which has been washed with appropriate solutions, usually acid/base, water, then brine, and finally dried over a dessicant like Na2SO4 or MgSO4).

Structure: Dimethyl sulfoxide (DMSO) is a polar aprotic solvent that can dissolve a wide range of organic compounds. The high dissolving power of DMSO makes deuterated DMSO (DMSO-d6) a common solvent for NMR. One of the major drawbacks of DMSO is the difficulty of removal after a reaction. Its high boiling point (189 C) makes removal by rotovap ...

The purpose of the rotovap is to remove low boiling organic chemicals, usually solvents, from a mixture of compounds. The rotary evaporator is the method of choice for solvent removal in the modern organic laboratory. The solvents or low boiling compounds are removed by a simple distillation. The rotovap is designed to be operated under a ...

This, however, applies only for small amount of water and only water. On practice, the last washing in a work up is usually made with brine or other salt solution. By drying organic phase you ...
