Organic Compounds Purification/Separation/Stabilisation TRIZ Cases
- Continuous Crystallization of Iodinated Aryls
Continuous crystallization with anti-solvents resolves the purity-productivity trade-off in iodinated aryl purification.
- Electrochemical Purification of Carboxylic Acid Aldehyde Impurities
Electrolytic cells oxidize aldehydes into carboxylic acids, eliminating solid solution impurities that hinder crystallization.
- Continuous Vitamin E Separation from Fatty Mixtures
Continuous transesterification isolates vitamin E and sterols from biological oils, preventing degradation during separation.
- Acetone Purification via Catalytic Impurity Conversion
Catalytic conversion transforms low-boiling impurities into higher-boiling ones, enabling efficient distillation and high-purity isopropanol production.
- [F-18]FEONM Purification via High-Pressure Diphenyl HPLC
High-pressure diphenyl column elutes [F-18]FEONM with ethanol solvent, removing toxic precursors for direct intravenous injection.
- Calcium Treatment for Olive Pomace Moisture Reduction
Adding calcium compounds to wet olive pomace creates compact solid particles that reduce residual moisture below 50 percent during mechanical separation.
- Sterically Hindered Nitroxyl Ether Preparation via Carbonyl and Hydroperoxide Reaction
A metal-catalyzed reaction of nitroxyl radicals with carbonyl compounds and hydroperoxides produces sterically hindered ethers.
