ABSTRACT:
This invention relates to a process for producing odourless dimethyl ether (DME) which is thus an excellent propellant. This dimethyl ether is produced from methanol, the methanol feed, prior to the reaction to form dimethyl ether, and/or the dimethyl ether product still containing odorants being treated with acidic materials, preferably acidic ion exchangers.
