Combine the organic extracts and dry with a small amount of sodium or magnesium sulfate. Transfer the dry organic extract into a 25 mL round bottomed flask and concentrate under reduced pressure (using the rotovap) until all of the solution can be placed in a polarimeter tube. Measure the optical rotation three times then

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.

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) 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 ...

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 ...

Here is a list of precautions you can take to avoid losing these volatile substances during your experiment: To remove solvent from a volatile product, avoid using a high vacuum line, and take care when working under reduced pressure. Recovering product from the vacuum trap is not a high-yielding experience. Reduce the vacuum strength on your ...

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.

Jan 30, 2022 The traditional approach to teaching Organic Chemistry, taken by most of the textbooks that are currently available, is to focus primarily on the reactions of laboratory synthesis, with much less discussion - in the central chapters, at least - of biological molecules and reactions. This is despite the fact that, in many classrooms, a majority of students are majoring …

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.

Organic chemistry is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds. Most organic compounds contain carbon and hydrogen, but they may also include any number of other elements (e.g., nitrogen, oxygen, halogens, phosphorus, silicon, sulfur). ...
