| titleOfInvention | Process for preparing methyl ethers |
| abstract | The invention relates to a process for preparing tertiary methyl ethers. According to the process the feedstock containing hydrocarbons is fed to a catalytic distillation reactor system, in which the isoolefines, in particular the C4 to C7 isoolefines, of the feed are reacted with methanol in the presence of a cation exchange resin in order to produce tertiary methyl ether products. The reaction product containing the ethers is removed from the distillation system as the bottoms product and, if necessary, it is subjected to an additional treatment for producing a gasoline component. The unreacted methanol is removed as the overhead product of the distillation. According to the invention, the distillate withdrawn mainly contains an azeotrope of C4 hydrocarbons and methanol, the C4 amount of which at least approximately corresponds to the C4 hydrocarbon concentra-tion of the hydrocarbon feed, a substantial amount of the unreacted methanol being removed in the form of said azeotrope. By means of the invention the need for a separate methanol washing unit is eliminated in the apparatus which considerably diminishes apparatus investment costs. |
