| Abstract: | Several etherification processes and catalysts for the synthesis of tertiary alkyl ethers from alcohols and iso olefins are reviewed. It points out NEXETHERS and DET are two important approaches for enlarging the availability of feedstock iso olefins and increase the ethers products. Compared with sulphonated ion exchange resins, zeolites possess such features as high thermal stability, without acid loss, high selectivity of tertiary alkyl ethers, less sensitivity of methanol/ iso olefin ratio and ease of reactivation. They are the development trend of catalysts for etherification. |
