Abstract
A process for producing an ether and an olefin from a hydrocarbon cut containing at least one tertiary olefin, comprises synthesis of at least one tertiary alkyl ether then fractionation to obtain an organic fraction (E1) which is enriched in the tertiary alkyl ether which is decomposed into a product containing at least one alcohol and at least one tertiary olefin, which is purified in a water washing extraction zone (L1) to obtain an aqueous fraction (A1) containing the major portion of the alcohol and a fraction (B1) containing the major portion of the tertiary olefin, at least a portion of fraction (B1) being sent to a separation zone (Co1) from which an aqueous liquid fraction (La1) and a liquid fraction (Lb1) containing the major portion of the tertiary olefin are recovered.
