Investigation of sustainable reactive distillation process to produce malonic acid from dimethyl malonate

Influence of Alkyl Chain Length of Alcohols on the Extraction Efficiency of 3-Methoxybutyl Acetate in Aqueous Solution (C5–C8 as Examples): Experimental Study, Thermodynamic Modeling, and Molecular Interaction Analysis

“…However, since water and 3-methoxybutyl acetate form an azeotropic system, traditional distillation processes cannot easily separate the azeotropic mixture, and special separation processes are therefore required. In industry, the methods commonly used for separating azeotropic mixtures are azeotropic distillation, , extractive distillation, , reactive distillation, , and liquid–liquid extraction. − Among them, liquid–liquid extraction is a simple and low-energy-consumption method that requires a simple device, making it ideal for separating and purifying various azeotropic mixtures . Therefore, liquid–liquid extraction is an effective method for separating 3-methoxybutyl acetate from its azeotropic solution.…”

Study on the Effect of Alkane Chain Length on the Extraction of Ethyl Acrylate from Aqueous Solution and Correlation of Thermodynamic Model

“…The production of EA is achieved by the esterification reaction of acrylic acid and ethanol, in which a mixture is inevitably formed with the by-product water. , Due to the close boiling points of EA and water, and the formation of azeotropic systems, it is difficult to separate them by conventional distillation processes. In industry, commonly used methods for separating azeotropic mixtures include azeotropic distillation, extractive distillation, and reactive distillation. , Although these methods can successfully separate azeotropic systems, they require specific conditions and consume more energy. Liquid–liquid extraction is an environmentally friendly method for separating azeotropic mixtures and does not require complex installations.…”
