DEHYDRATION AND ESTHERIFICATION OF CRUDE METHANOL-SUPPLIED RAW MATERIAL |
摘要 |
An improved process for reacting crude aqueous methanol feedstock with isoolefinic hydrocarbons to produce C5<+> methyl isoalkyl ethers, which comprises: contacting the aqueous methanol feedstock with a liquid hydrocarbon extractant rich in C4<+> isoalkene under liquid extraction conditions; recovering an aqueous phase containing the major amount of water introduced with the feedstock; recovering an organic extract phase comprising the hydrocarbon extractant and a major amount of methanol introduced in the feedstock; and reacting the extracted methanol and C4<+> isoalkene in contact with an acid etherification catalyst under catalytic reaction conditions to produce ether product. |
