General description

2-Butanone, also known as methyl ethyl ketone (MEK), is a commonly used organic solvent. Due to its low boiling point, low viscosity, ability to accommodate high solid concentrations, and wide diluent tolerance, it has wide applications in the polymer industry and as a solvent in adhesives and paints.

Application


  • Lipid and Volatile Profiles of Finnish Oat Batches of Pure Cultivars: Investigates the effects of storage on volatile formation including 2-Butanone in food processing, which is significant for food scientists and researchers looking into food preservation and flavor profiling (Puganen et al., 2024).

  • Changes in Volatile Compounds and Lipid Oxidation in Various Tissues of Nile Tilapia During Ice Storage: Examines the impact of storage on the volatile compound profiles of seafood, including 2-Butanone, valuable for food scientists and technologists working with seafood preservation and quality assessment (Karbsri et al., 2024).
