| titleOfInvention | Simple manufacturing and purification technology for high purity propofol |
| abstract | A process for manufacturing Pure Propofol with a purity of more than 99.90% is disclosed, said process comprising dissolving Crude Propofol in a solvent in which it is soluble to form a solution, treating the solution with aqueous alkali to form an aqueous alkali layer and a solvent layer, separating the aqueous alkali layer from the solvent layer using a phase separation technique, distilling off the solvent from the solvent layer, and distilling a residue of the solvent containing Propofol using steam or boiling water in a presence of dilute alkali and antioxidant like metabisulfite, under normal pressure or mild vacuum. |
