| 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 |
| General description: | 2-Butanone is an organic compound that can be used in the chemical industry as an oxidative reaction activator, extractive agent, solvent, and chemical intermediate. It can be produced by the catalytic dehydrogenation of 2-butanol. |
