Abstract
Disclosed is a high yield, high selectivity and high conversion method to produce Dimethyl Carbonate (DMC) from carbon dioxide (CO2) and methanol (MeOH) using optimized concentration of ethylene oxide as water scavenger. The method provides an alternative and optimized solution towards the problem of formation of water in DMC synthesis by reporting optimal feed ratio and scavenger to MeOH feed ratio. The disclosure also discloses an optimal pressure condition that could have significant impact on economy of compression of the feed to the DMC reactor.
Claims18
A method to produce DMC, the method comprising:
- adding to a reactor reactants comprising CO2 and MeOH for a first reaction,
- wherein a pressure in the reactor is from 1 bar to 100 bar,
- a temperature in the reactor is from 100° C. to 200° C., and
- the reactor operates in a continuous mode with a continuous flow of feed of the reactants into the reactor and products leaving the reactor.
