ABSTRACT:
A method is disclosed combining the process for the hydration or etherification of light linear olefins, such as the production of diisopropyl ether (DIPE), with the process for the etherification of C.sub.4 + or C.sub.4 hydrocarbons containing isobutylene to produce alkyl tertiary butyl ether or ether-rich gasoline in a manner which effectively dewaters alkanol using the iso-olefin hydrocarbon feedstream as extractant. The combined process leads to the production of isopropyl tert-alkyl ethers. In the integrated process the high octane ethers produced may include methyl tert-butyl ether, methyl tert-amyl ether, isopropyl tert-butyl ether and diisopropyl ether. The process also results in the production of a gasoline stream rich in high octane ethers.
