Application
2-Butanonecan be used as a solvent:
- To synthesize waterborne polyurethanes by reacting polyols and diisocyanates via polymerization reaction.
- In the Al-catalyzed chemoselective coupling of oxetanes and carbon dioxide to synthesize six-membered cyclic carbonates.
Features and Benefits
- Low-boiling solvent
- High power of dissolution
- High ratio of dissolved matter to viscosity
- Miscible with a wide range of hydrocarbonswithout affecting the solid′s content or viscosity
- Favorable volume/mass ratio due to its low density
- Fast evaporation rate
