Descrizione

Applicazioni

• Adaptable heat pump-assisted dividing-wall column design for intensified downstream processing of bio-propionic acid: This article describes the esterification and separation processes in which methyl acetate is used to achieve higher purity levels in chemical production. This method enhances the recovery of methyl acetate at a purity of 99.9% (T Janković, AJJ Straathof, AA Kiss - Separation and Purification Technology, 2024 - Elsevier) (Source).
• Beta-irradiation of biomass in the presence of 1-alkyl-3-methyl-imidazolium ionic liquids: Discusses the unexpected product formation during the beta-irradiation of biomass, where methyl acetate plays a crucial role in the chemical reactions of biomass conversion processes (AF Lehrhofer, M Bacher, H Hettegger, S Böhmdorfer - Cellulose, 2024 - Springer) (Source).
• Supramolecular Gels Based on C3-Symmetric Amides: Explores the application of methyl acetate in the formation of supramolecular gels aimed at environmental applications such as anion-sensing and dye removal from water, demonstrating its versatility in advanced material science (G Kuppadakkath, SS Jayabhavan, KK Damodaran - Molecules, 2024 - mdpi.com) (Source).
