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 an α,β-unsaturated aldehyde with a trihydrocarbyl orthoester to form an α,β-unsaturated acetal and conversion of the α,β- unsaturated acetal to an ether through hydrogenation and hydrogenolysis.
本发明涉及一种制备醚的方法,特别是不对称醚,且最好适用于作为润滑剂配方基础油的醚。具体而言,该方法涉及将α,β-不饱和醛与三烷基正酯发生反应,形成α,β-不饱和
缩醛,并通过加氢和氢解将α,β-不饱和
缩醛转化为醚。
