Intensification of Ethylene Carbonate Synthesis via Microwave-Induced Phase-Change Cycles.

ABSTRACT: This study reports for the first time on the application of microwave (MW) heating under ambient pressure reflux conditions to intensify the transesterification reaction of ethylene glycol with dimethyl carbonate (DMC) for the synthesis of ethylene carbonate (EC), a relevant industrial compound for polycarbonate products, lubricants and li-ion batteries. Conventional heating (CH) methods often require high-temperature autoclave systems to achieve elevated temperatures and suppress vaporization of the reactant DMC (bp ≈ 90 °C). However, these systems usually entail extended reaction times and significant process cost. It is demonstrated that application of the MW-assisted reflux technique to the aforementioned transesterification reaction intensifies the energy transfer rate to the reactor
