Production technology of diethyl carbonate

Thread Content

The current production of diethyl carbonate in China mostly uses dimethyl carbonate as a raw material, which undergoes transesterification with ethanol to produce diethyl carbonate as well as methylethyl carbonate. Due to the coexistence of diethyl carbonate and methyl ethyl carbonate in this reaction, the yield of diethyl carbonate is not high. Recently, a technique has been proposed for the ester exchange of propylene carbonate with ethanol to produce diethyl carbonate. This technology achieves high selectivity and yield for diethyl carbonate,” but due to the low equilibrium constant of the transesterification reaction between propylene carbonate and ethanol, special reaction reactors are required. I would like to ask all my friends and experts from Sichuan – does anyone have expertise in this area of production technology? What is the level of maturity of this technology? What is the market situation for diethyl carbonate? How does this special reaction reactor achieve the production of diethyl carbonate through this reversible reaction? Active participation is welcome; those who speak enthusiastically and come up with feasible ideas will receive extra points! ! ! !
