Organic products: "carbon-based compounds and hydrocarbons. May contain many other elements, including hydrogen, nitrogen and oxygen." ~Wikipedia
Is the process of making a desired product by choosing suitable available reagents and carrying out reactions in a specific order. Each stage in an organic synthesis normally requires three steps; reaction, separation and purification.
- Reaction: The reaction chosen depends on the available reagents and efficiency. Many organic reactions do not give 100% yield, so the route is chosen which is likely to provide the best yield.
- Separation: The product is usually mixed with other by-products and unreacted material and needs to be separated in some way. This may be done by filtration, distillation, steam distillation, solvent extraction, chromatography, etc. The method chosen depends largely on the state of the product and the nature of the impurities.
- Purification: The product may be purified by distillation, recrystallisation, sublimation etc. The final purity is usually established using the melting or boiling temperature of the product. A pure product has a sharp melting/boiling point.
