PROCESS FOR PREPARING METHYL-C4-C5-TERTALKYL ETHERS

FIELD: high-octane additives to motor fuels. SUBSTANCE: methyl-C4-C5-tertalkyl ethers are prepared by reacting hydrocarbon fraction containing C4-C5 tertiary olefins with methanol at 40-50 C in the presence of cationite in hydrogen form and ortho-tert butyl phenol and/or tert butyl ether of orthoter...

Zusammenfassung:FIELD: high-octane additives to motor fuels. SUBSTANCE: methyl-C4-C5-tertalkyl ethers are prepared by reacting hydrocarbon fraction containing C4-C5 tertiary olefins with methanol at 40-50 C in the presence of cationite in hydrogen form and ortho-tert butyl phenol and/or tert butyl ether of orthotert butyl phenol of 0.01-0.200 wt % based on initial hydrocarbon mixture. EFFECT: greater efficiency and higher selectivity of the process and longer service life of the catalyst.
