Abstract
Provided are two-stage processes by which primary alcohols such as ethanol or 1-butanol are converted into distillate-range ethers and olefins utilizing Guerbet coupling followed by intermolecular dehydration. The ethers can be used, for example, as cetane-improvers in diesel fuel, while the olefins can be hydrogenated to afford paraffins.
