Analysis of the synthesis of 1,1-dibutoxyethane in a simulated moving-bed adsorptive reactor

Sorption enhanced reactive process for the synthesis of glycerol ethyl acetal

“…In most of the aforementioned works, advantage is taken from the sorption and catalytic properties of ion exchange resins. This dual behaviour presented by this type of materials, especially by Amberlyst-15, has demonstrated to be particularly effective, even for more complex chromatographic reactors as the simulated moving bed reactor [21][22][23][24][25][26][27][28]. Such ion exchange resins are constituted by crosslinked styrene divinylbenzene copolymers functionalized with acid sulfonic groups.…”

Conversion improvement for catalytic synthesis of propylene glycol methyl ether acetate by reactive chromatography: Experiments and parameter estimation

“…Chromatographic reactors are especially beneficial when the reaction is equilibrium-limited, where the separation of products from the reaction site suppresses the backward reaction, and thus drives the conversion towards completion. Due to these advantages, numerous studies have evaluated reactive chromatography for different applications such as biodiesel production [1], glucose isomerization [2][3][4], hydrolysis of acetates [5], alkylation [6], etherification [7], dehydrogenations [8] and acetalizations [9][10][11].…”

Simulated Moving Bed Reactor

“…The SMBR production of acetals, namely, diethyl acetal (DEE) , dimethyl acetal (DME) (Pereira et al, 2008a), dibutyl acetal (DBE) (Graça et al, 2011), and glycerol ethyl acetal (GEA) (Faria, 2014), was also evaluated in our laboratory; indeed, DEE was the first studied system that uses an SMB-based technology for the simultaneous production and separation of acetal by means of ion-exchange acid resins (Rodrigues and Silva, 2004).…”

“…This integration was evaluated for the production of DEE (Silva et al, 2009). (Pereira et al, 2008a); DEE: diethyl acetal ; DBE: dibutyl acetal (Graça et al, 2011). The use of azeotropic distillation to break azeotropes is expensive, which will be reflected on the overall costs of the process.…”
