Abstract
In a process for producing tertiary alkyd ethers from an olefinic hydrocarbon feedstock, undesirable normal alkanes are removed from the process by passing at least a portion of a hydrocarbon process stream to an alkane isomerization zone to convert normal alkane to isoalkane and passing the alkane isomerization zone effluent to a separation zone to remove the isoalkane. Since no normal alkane is discharged from the process, the loss of valuable olefins, which have boiling points close to normal alkane, is prevented and olefins are retained in the process and converted to the appropriate tertiary alkyl ether. The result is an increase in the ether yield.
