Amino Compound Purification/Separation TRIZ Cases
- Ion Exchange Phenol Removal in Aniline Purification
Ion exchange materials remove phenol from crude aniline, bypassing complex distillation towers required by similar boiling points.
- Ethyleneamine Purification via Extractive Distillation
Triethylene glycol extractive distillation isolates diethylenetriamine from monoethylene glycol, reducing energy consumption and by-product formation.
- Partial Condenser in Vacuum Distillation for IPDA Purification
A partial condenser pre-cools vapor streams in the first vacuum distillation column to enable efficient reflux recycling.
- Purified Amine Compound Production via Halide Salt Segmentation
Sequential halide salt formation, liquid-liquid extraction, and precipitation yield 97.5% pure amine compounds.
- Tolylenediamine Dehydration via Two-Stage Vacuum Distillation
Two-stage vacuum distillation dehydrates tolylenediamine by separating bulk water removal from final purification under specific pressure conditions.
- Biomass Pyrolysis Product Recovery via Quenching and Solvent Contact
Quenching biomass pyrolysis effluent with organic fluid and contacting solvent recovers aromatics while handling complex mixtures.
- Bendamustine Ester Synthesis via Oxalyl Chloride and DMF
Oxalyl chloride and dimethylformamide selectively substitute terminal hydroxyl groups to produce bendamustine esters.
- P-diphenyl Compound Derivative Mixture for Organic Electronics
A p-diphenyl compound derivative mixture enhances charge mobility in organic electronic devices.
- Cardanol Production from Cashew Nutshell Liquid
Acetic anhydride protects cardanol during distillation, preventing polymerization losses and improving yield.
- Aniline Distillation Bottom Product Dilution
Diluting aniline distillation bottoms with methanol prevents solidification and pipeline blockages.
- Cyclic Monourea Conversion to Ethylene Amine
Reactive separation converts cyclic monourea into ethylene amine via urea transfer, avoiding degradation from strong bases.
