On C5 etherification technology
Thread Content
Experts: Could someone please provide an introduction to carbon pentyl etherification technology, as well as information on production costs and other related aspects? Thank you!
Under the action of large-pore strongly acidic cationic resin catalysts, and at certain temperatures, pressures, space velocities, and alcohol-to-oil ratios, the light gasoline fractions contain tertiary olefins such as 2-methyl-1-butene, 2-methyl-2-butene, and certain C6 tertiary olefins, which react with methanol to produce ethers like methyl tert-butyl ether and methyl tert-hexyl ether. CH3 CH3 │ │ R－CH = C－CH3 + CH3OH R－CH2－C－O－CH3 R－CH2－C = CH2 │ │ CH3 CH3 (R: –CH3, –CH2CH3, –CH2CH2CH3) Side reactions: 1. Olefin polymerization: Olefins polymerize to form dimeres and trimers. 2. Alkylation reaction of heteroolefins: 3. Dehydration reaction of methanol: Methanol undergoes dehydration to form dimethyl ether at temperatures of 120–140°C; it is essential to strictly control the reaction temperature so that it does not exceed 90°C. 4. Resin catalysts have adsorption properties and can absorb some basic nitrogen compounds in gasoline during etherification modification.
Are you going to make TAME, tert-butyl methyl ether?
