Abstract
The present invention relates to a process for preparing ethers, particularly unsymmetrical ethers, and preferably ethers suitable for use as base stocks for lubricant compositions. In particular, the process involves the reaction of a branched-chain aldehyde and a branched-chain alcohol to form an enol ether and conversion of the enol ether to a saturated ether by reduction.
