Carboxylic Acid Amide Separation/Purification TRIZ Cases
- Amido Monomer Composition Using Metal Chelates for Storage Stability
A carbonyl-ligand metal chelate suppresses self-polymerization and coloration in amido monomers during high-temperature storage.
- N-Vinyl Carboxylic Acid Amide Purification by Two-Stage Crystallization
Cooling precipitation followed by MEK–C6–C7 hydrocarbon crystallization purifies N-vinyl monomer for improved polymerizability and productivity.
