PROCEDE DE PRODUCTION D'OLEFINE TERTIAIRE PAR DECOMPOSITION D'ETHER ALKYLIQUE TERTIAIRE COMPORTANT UNE PREMIERE ETAPE DE PURIFICATION PAR LAVAGE A L'EAU

A process for the production of a tertiary olefin by decomposition of a tertiary alkyl ether comprises: (a) a decomposition stage of the ether in a reaction zone (R1) containing a decomposition catalyst, to produce a product (P) comprising an alcohol, a tertiary olefin, non-decomposed ether and ligh...

Summary:A process for the production of a tertiary olefin by decomposition of a tertiary alkyl ether comprises: (a) a decomposition stage of the ether in a reaction zone (R1) containing a decomposition catalyst, to produce a product (P) comprising an alcohol, a tertiary olefin, non-decomposed ether and light compounds; (b) a purification stage in a water extraction zone (L1) in which an aqueous fraction (A1), containing most of the alcohol initially present and a fraction (B1) containing the tertiary olefin, water, ether and light compounds (with a very low quantity of alcohol), are obtained. The process includes a stage: (c) in which (B1) is passed to a separation zone (Co1) from which a liquid aqueous fraction(La1) and a liquid organic fraction (Lb1) are obtained. (Lb1) contains the tertiary olefin, ether and some light compounds.
