Name: 4-(Hydroxymethyl)-1,3-dioxolan-2-one. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 4-(Hydroxymethyl)-1,3-dioxolan-2-one, is researched, Molecular C4H6O4, CAS is 931-40-8, about Development of two plant-wide glycerol carbonate production processes: Design, optimization and environmental analysis.
This work firstly presents the rigorous modeling of the two plant-wide glycerol carbonate (GC) production processes through the transesterification reaction of glycerol (GLY). One is the separated reaction and distillation (SRD) process, and the other is the reactive distillation-based (RD) process. This work covers the thermodn. and kinetic verification, the rigorous simulation of the two processes, and optimization of the proposed processes based on simulated annealing method. From optimization, it is found that the RD process reduced about 33.1% cost from the SRD process. Also, carbon emission analyses are performed on the two optimized processes, in which the CO2 emission amount per unit amount of GC formation (CO2-e, in kg CO2/kg GC) are calculated It is reported that the RD process reduces 36.1% of CO2 emission (CO2-e=0.207) compared with the SRD process (CO2-e=0.322).
