PROCESS FOR PREPARING METHYL-C-C-TERTALKYL ETHERS Russian patent published in 1999 - IPC

Abstract RU 2126377 C1

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.
