Kinetic modelling of acid-catalyzed liquid-phase dehydration of bio-based 2, 3-butanediol considering a newly identified by-product and an updated reaction network

Prospects on bio-based 2,3-butanediol and acetoin production: Recent progress and advances

“…sulphuric acid, p-toluenesulfonic acid, phosphoric acid), the reaction temperatures and the mode of operation and unit operations used (e.g. batch or continuous processing, distillation) (Bai et al, 2020).…”

A perspective on catalytic production of olefinic compounds from biomass

“…Solid acid–base bifunctional catalysts with basic nature are effective, such as scandium oxide. 163 The yield of butadiene reached about 90% with scandium oxide-based catalysts. 164 Metal phosphate catalysts have been also tested.…”

“…However, simple acid-catalyzed dehydration of 2,3-butanediol produces butanone (frequently called as methyl ethyl ketone or MEK) rather than butadiene or 3-buten-2-ol intermediate. 163 Dehydration to 3-buten-2-ol or butadiene requires removal of hydrogen at the terminal positions (1- and 4-). To obtain such selectivity, the reaction should be driven by a base instead of acid, and the base site is better to be sterically hindered to control the accessibility toward the terminal positions.…”

Kinetic Data for Continuous Processes from Liquid‐Liquid Loop Reactor Experiments

“…Such parameters include the selection of the appropriate kinetic model, knowledge of possible side reactions, the rate of reaction at various temperatures T, and the reaction enthalpy. At present, these parameters are commonly obtained in batch [1][2][3][4][5][6] or continuously operated stirred tank reactors (CSTR) [3,7].…”
