Application

DME can be used as precursor for the production dimethyl sulfate by treatment with sulfur trioxide. Dimethyl sulfate is employed as a versatile methylating agent in chemical synthesis. It is also used as a starting material for preparation of dimethyl sulfide, acetic acid, unsaturated and saturated hydrocarbons, and formadehyde.
Dimethyl ether (DME) can be used as a precursor to synthesize methyl acetate, oligomeric oxymethylene ethers (OMEs), polyoxymethylene dimethyl ethers (DMMx) and light olefins.

General description

Dimethyl ether (DME) is the simplest aliphatic ether used as a reactant as well as a solvent in organic synthesis. It is used as a precursor for the preparation of important useful organic compounds. DME is also used as an aerosol propellant.

Packaging

Supplied in a Sure/Pac™ cylinder and has a brass needle valve with a male 1/4" NPTF outlet thread installed. Before using the cylinder, ensure that the valve is closed, then remove the galvanized steel hex cap that seals the outlet valve.
