General description
Dimethyl ether (DME) is the simplest aliphatic ether used as a reactant as well as a solvent in organic synthesis. It is also used as a precursor for the preparation of important useful organic compounds such as dimethyl carbonate, methyl acetate, propylene and chloromethyl ether.
Application
DME can be used as a precursor for the preparation of versatile methylating agents such as dimethyl sulfate and trimethyloxonium tetrafluoroborate.

We proposed a method for the deodorising and dewatering of biosolids. In the proposed method, liquefied dimethyl ether (DME) was used as an extractant for odorous components and water. We developed a bench-scale experiment to almost completely deodorize and dewater
