- Practical Techniques in Organic SynthesisMaking an organic compound in the lab is only half the job: the crude product is always mixed with unreacted starting materials, by-products and…
- Quickfit ApparatusQuickfit apparatus is a set of glassware with standard ground-glass joints that fit tightly together, so no corks or bungs are needed and vapours…
- Filtration under Reduced PressureFiltration under reduced pressure (also called vacuum or suction filtration) separates a solid from a liquid much faster than gravity filtration…
- RecrystallisationRecrystallisation purifies an impure organic solid.
- Melting Point DeterminationMeasuring the melting point of a solid is a quick test of its purity, and can help identify it.
- Identifying Functional GroupsIn synthesis and analysis you often need to find which functional groups a compound has.
- Aliphatic Synthetic RoutesAn aliphatic synthetic route converts one non-aromatic compound into another in one or more steps.
- Aromatic Synthetic RoutesAromatic synthetic routes start from benzene or phenol.
- Planning Multi-Stage SynthesesA multi-stage synthesis converts a starting material into a target molecule through two or more steps.
