Protective Groups - Organic Chemistry

A protective group (also referred to as protecting group) is a reversably formed derivative of an existing functional group in a molecule. The protective group is temporarily attached to decrease reactivity so that the protected functional group does not react under synthetic conditions to which the molecule is subjected in one or more ...

Concentrate the mixture on the rotovap until most of the solids have crashed out. Filter the solids. Usually a buchner funnel will be used. Wash the filter cake with a minimum amount of solvent. Use a solvent mixture/ratio which is higher in ratio of anti-solvent:solvent than the initial solvent mixture used to dissolve your impure pdt.

What are Applications of a Rotary Evaporator? - Rotovap

Dec 20, 2019 A rotary evaporator is electronically controlled so that the rotation of the flask can be kept at a constant speed, and the mixture can form a film on the inner surface of the flask, creating a larger surface for heating. All of these factors contribute to the faster evaporation speed of solvent, which means higher efficiency and better accuracy.

Dimethyl Sulfoxide (DMSO) - Common Organic Chemistry

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 very ...

Most reactions in organic chemistry are done in solution. After the reaction is finished however, a chemist must remove the solvent in order to isolate the product of the reaction. A rotary evaporator (“rotovap”) is an extremely useful tool for accomplishing this task. The solution containing product starts off in a round-bottomed flask.
