ABSTRACT:
Secondary alcohols are converted to symmetrical secondary alkyl ethers in high selectivity. The method employs acidic solid metallosilicate catalyst particles to accomplish the etherification by selective intermolecular dehydration of secondary alcohol to form di-secondary alkyl ethers. Preferably, the catalysts are solid shape selective aluminosilicate particles, especially zeolite such as ZSM-5, zeolite HY and zeolite Beta. Continuous separation of by-product olefin and ether during the etherification reaction improves selectivity.
