CONTINUOUS PROCESS FOR CONVERSION OF CRUDE METHANOL IN TERTIARY METHYL-ALCHEMICAL ETHERS, PROCESS FOR CONVERSION OF RAW METHANOL LOAD INTO TERTIARY METHYL-ALKYLIC PRODUCT AND CONTINUING ETERIFICATION AND SEPARATING LOAD SYSTEM

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.
