Product Name:Ethyl methyl carbonate
CAS Number:623-53-0
Molecular formula:C4H8O3
Molecular Weight:104.1

Currently, the synthesis of Ethyl methyl carbonate in open literature can be mainly categorized into phosgene method, carbonyl oxide method, and transesterification method. EMC synthesis from transesterification of DMC and EtOH is known for its mild reaction conditions, ease of control, and low environmental pollution, making it the most promising process route. Ethyl methyl carbonate is selectively synthesized from dimethyl carbonate and ethanol via catalytic reactive distillation ( RD) over heterogeneous MgO/HZSM-5. It is shown that 2.3%MgO/HZSM-5 catalyst has high catalytic activity with 99.4% conversion of ethanol ( EtOH) and 98.1% selectivity to EMC in an RD column[3].

Steps:

2.3.1 Typical procedure for the synthesis of EMC
A mixture of DMC (9.000g, 0.1mol), DEC (11.800g, 0.1mol) and catalyst (0.200g, 2wt.%), was charged into a 50mL flask equipped with a magnetic stirring and a reflux condenser. The reaction mixture was then heated to 100°C with continuous stirring. After 24h, the mixture was cooled to room temperature. And the product was filtered and analyzed by a gas chromatograph (GC, Agilent-7890A) equipped with a flame-ionized detector. In the reusability experiment, catalysts were separated by filtration and washed using methanol (10mL×3), then dried in air at 150°C for the next reaction.
