When two immiscible liquids are placed in a separatory funnel, two layers are seen. The denser solvent will be the bottom layer. Most halogenated solvents are denser than water, most non-halogenated solvents are less dense than water. If you are not sure which layer is which, add a drop of water and see which layer it joins.

Filtration of the reaction products. Even if the flask was 5000 cm3 large, a lot solvent was in it and a lot reagent, we only got 50-100 g of product.

8 polairebindingen en waterstofbruggen: oplosbaarheid in water

8 polairebindingen en waterstofbruggen: oplosbaarheid in water

During a workup of a reaction we often need to wash the product with different solvents, in this case water and methanol. Why is this needed? Because most reaction what is performed between A and B what are mixed to produce compound C (the product what we want) D, E, F, G, H… (things what we do not need) are also produced. To remove the side products (D, E, F, G, H…) different techniques should be used to purify the product of the reaction. In this case I used water to wash down the excess s

When doing an organic chemical reaction and working with non miscible solvents like ether/water, dichloromethane/water, , toluene/water, chloroform/water, ect., it often happens that while you started from a completely transparent solution and added a solvent what will probably dissolve only the compound what you need, or not need, some insoluble participate forms between the two non miscible phase. Just as in  this case.

Buchner flask may also be called a vacuum flask, filter flask, side-arm flask, or Kitasato flask. It is a thick-walled Erlenmeyer flask that has a short glass tube and hose barb on its neck.

Blog: “En hoeveel uur gaat dat ongeveer kosten?” Het is de op één na meest gestelde vraag in acquisitiegesprekken.* Uitstekende vraag. Als ik daar toch eens een pasklaar antwoord op had.
