Process for preparing tertiary alkyl ethers |
| abstract |
A process for preparing tertiary alkyl ethers from isoolefins and aliphatic alcohols in the presence of a catalyst in the form of sulphonated styrene-divinylbenzene resins, characterized in that both the reaction leading to the formation of the tert-alkyl ether and the separation of the tert-alkyl ether from the hydrocarbons and compounds which accompany it take place in a single plate fractionating apparatus, in which some of the plates are provided with beds of catalyst in the form of spherules suitable for preparing said tert-alkyl ether, the ether obtained being withdrawn as a substantially pure bottom product. |
