There hasn't been much emphasis on DME in recent years, at least in comparison with other homemade or commercial fuels. That may change.

Hi, all

Can anyone tell me where I can find the reaction conditions for the
hydrolysis of dimethyl ether?

CH3OCH3 + H2O <-> 2 CH3OH

Dimethyl ether doesn't hydrolyze. You would need strong aqueous acid,
high temps, and a long wait. Note that dimethyl ether is a gas at
ambient conditions. Run it through ZSM-5 and make high aromatics
gasoline.
