SELECTION OF SOLVENT
The solvent selected for a particular reaction should not have any environmental pollution and health hazard. Green chemistry suggests the use of alternative solvents. Some common alternate solvents are water, super critical fluids like carbon dioxide, ionic liquids, solvent free processes and bio-solvents.<br>
03
AQUEOUS PHASE REACTIONS
Organic reactions carried in aqueous phase i.e. using water as solvent are known as aqueous phase reactions. Water is always a preferred solvent, it causes no environmental pollution and is never a health hazard to human beings working with it. Using water as a solvent offers many advantages such as low cost, non-inflammable, non-carcinogenic and simple operation.<br>
