Descrizione generale
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.
Applicazioni
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

Tungstated zirconia is a robust solid acid catalyst for light alkane (C(4)-C(8)) isomerization. Several structural models for catalytically active sites have been proposed, but the topic remains controversial, partly because of the absence of direct structural imaging information on the

We present a new experimental configuration for the study of size-dependent, angle-resolved photoelectron and photoion spectra of weakly bound ultrafine aerosol particles targeted at particle sizes below ~20 nm. It combines single photon ionization by a tunable, table-top vacuum ultraviolet
