Amino Compound Purification/Separation TRIZ Cases
- Liquid-Phase Alkylation of Para-Anisidine to N-Methyl-Para-Anisidine
Separate feeding of reactants prevents mixer clogging while high selectivity suppresses dimethyl derivative formation during catalytic reduction.
- Xylylenediamine Purification via Solvent Extraction and Hydrogenation
A method converting xylene to xylylenediamine through solvent extraction of dicyanobenzene followed by liquid phase hydrogenation.
- Perfluoropolymer Membrane for Ionic Liquid Dehydration
Perfluoropolymer membranes separate water from ionic liquids, eliminating costly substance loss and maintaining stability across varying concentrations.
- EDA Purification via Elevated Pressure Distillation
Operating above 4.8 bara eliminates azeotropic constraints, removing nitrogen contaminants without adding water.
- Levoamphetamine Synthesis via Catalytic Hydrogenation
Replacing cold organometallic reagents with catalytic hydrogenation eliminates flammability hazards while maintaining enantiomeric purity.
