Beschreibung

Anwendung

• Machine-Learning-Based Kinetic-Free Hybrid Gray-Box Model to Predict Sulfuric-Acid-Catalyzed Esterification Reaction.: Describes a new machine learning model to optimize the esterification reaction process, which can potentially include the use of 2-butanol as a reactant or solvent (Wen X et al., 2024).



• Dynamic microbial and metabolic changes during Apulian Caciocavallo cheese-making and ripening produced according to a standardized protocol.: This research investigates the role of microbial communities and their metabolic activities in cheese production, where solvents like 2-butanol may be used in analytical methods (Vacca M et al., 2024).



• Interruption of p38(MAPK)-MSK1-CREB-MITF-M pathway to prevent hyperpigmentation in the skin.: Discusses the biochemical pathway involved in skin pigmentation, where 2-butanol may be employed in experimental procedures or as a solvent (Kim SH et al., 2024).
