FOERFARANDE FOER FRAMSTAELLNING AV RENA ALKANYL-TERT.-ALKYL-ETRAR OCH HUVUDSAKLIGAST AV FRAON ISO-OLEFIN OCH ALKANOL BEFRIADE KOLVAETERAFFINADER |
摘要 |
A process for the preparation of pure alkyl tertiary alkyl ethers and hydrocarbon raffinates which are substantially free from tertiary olefins and alkanols. An alkanol and a hydrocarbon mixture containing at least one tertiary olefin are contacted with the alkanol being present in a stoichiometric excess. The reaction product is removed from the reaction zone and excess alkanol in the reaction product or a partial stream thereof is absorbed on a synthetic ion exchanger containing groups which exchange cations or anions or mixtures of such ion exchangers. After absorption of at least a portion of the alkanol on the synthetic ion exchanger, the alkanol is desorbed by contacting the same with a hydrocarbon mixture containing at least one tertiary olefin. |
