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.

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.

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.
