Selective hydration of dihydromyrcene in ionic liquids

Acid catalysed direct hydration of dihydromyrcene to dihydromyrcenol proceeds selectively in ionic liquid media. By making use of the tuneable physicochemical properties of ionic liquids, and depending upon the process requirement, either biphasic or triphasic systems can be developed. The selectivity to dihydromyrcenol remains extremely high over a wide range of reaction conditions.
