ResourceRecycling the undesired enantiomer of Naproxen
This context/problem-based learning (C/PBL) resource is part of a collection we have commissioned for you to use with your undergraduate students. This 5 credit module is based on the following scenario:Your students work for a company that produces (S)-naproxen, a non-steroidal anti-inflammatory drug (NSAID), via a racemic method. Whilst (S)-naproxen ...

ResourceThin layer chromatography
The technique of Thin Layer Chromatography (TLC) is normally used as an analytical method to follow the progress of a reaction, to analyse mixtures or to establish conditions for a preparative separation of compounds using column chromatography. The stationary phase (often silica) is coated on plastic or aluminium plates. The ...

ResourceColumn chromatography
The separation of mixtures produced in chemical reactions is often carried out by passing the mixture through a stationary phase of silica held in a column. Solvents move compounds at different rates through the silica allowing them to be separated into fractions by collecting the emerging solvent. This can ...

ResourceHeating under reflux
The term ‘reflux’ describes an arrangement in which a reaction is carried out in a boiling solvent with the vapour being condensed and returned to the reaction vessel. Refluxing is carried out when reactions need to be heated to give a reasonable yield of product in a reasonable time. ...

ResourceDean-Stark apparatus
There are many equilibrium reactions that yield water as a co-product. It is the co-produced water that prevents a high yield of product being obtained. The removal of the water is necessary to drive the reaction to completion and this is done using Dean-Stark apparatus. The reaction is carried out ...

ResourceSteam distillation
The extraction of a crude mixture containing water-insoluble material (such as natural products) can be achieved by co-distillation with steam. Video: Steam distillation video
