“…Therefore, additional process engineering is required to forward the reaction of DMC and phenol to MPC. Among the products, methanol is the most volatile component in the mixture; so, it is attractive to remove methanol from the reaction system by reactive distillation to enhance the yield of MPC from DMC, as suggested by some reports [23,24].…”

The transesterification of dimethyl carbonate with phenol to methyl phenyl carbonate (MPC) was investigated on novel catalysts such as titanium diisopropoxide bis(ethyl acetoacetate) and titanium dibutoxide bis(ethyl acetoacetate) in a closed batch reactor at 185-206°C under high pressure. The produced methanol could be removed efficiently by reactive distillation in order to overcome the equilibrium. The prepared catalysts have higher resistance to water than titanium alkoxides. Phenol conversion as high as 86.4 % with an MPC selectivity of 99.4 % was achieved under optimal reaction conditions within 9 h. Most of the catalytic activity was retained after repeated use for ten times.

“…Moreover, as FT reactions are highly exothermic, RD also impacts energy costs as the heat of reaction can be used for separation . RD technology can also be improved further through energy integration to reduce energy consumption and increase energy efficiency . Finally, RD can increase selectivity for intermediate products in a multi‐product system.…”

Advanced nonlinear programming (NLP) strategies based on equation-oriented (EO) process models are leading to significant improvements in computer-aided process engineering. The EO paradigm allows the development of large, integrated optimization platforms that expand the scope of continuous optimization tasks in process engineering. In particular, these platforms deploy significantly faster NLP strategies than in commercial simulation tools. Moreover, they exploit exact derivatives and system structure in order to consider much larger and more challenging systems. Finally, they allow the incorporation of much more general models, such as multi-level optimization and complementarity constraints. For process optimization this allows the treatment of extended models for complex phase equilibrium and process separations. These advances facilitate the optimization of novel integrated systems that arise in process intensification. Several separation case studies are presented that illustrate these optimization concepts and demonstrate their effectiveness for hybrid membrane/distillation separations and reactive distillation systems that typify novel systems in process intensification.

“…1,2 Diphenyl carbonate (DPC), a building block, was oen employed for the phosgene-free synthesis of PC by melt trans-esterication with bisphenol-A, and was also used for the production of pharmaceuticals, polymer materials, ne chemicals, etc. [3][4][5] It was, therefore, necessary to develop efficient and environmentally benign synthetic routes to replace the highly toxic synthesis via phosgene. Among the alternative routes (phosgene method, 6,7 oxidative carbonylation, 8,9 trans-esterication, 10,11 etc.…”
