<p>A process for efficiently producing a high-purity oxygenic compound with a high volume resistivity; and a lubricating oil containing the high-purity oxygenic compound. The process, which is for producing a high-purity oxygenic compound selected from the group consisting of polyvinyl ether compounds, polyalkylene glycol compounds, polyol ester compounds, cyclic polyether compounds, and carbonate compounds, is characterized by comprising the step of treating with an adsorbent at least one crude oxygenic compound selected from the group consisting of crude polyvinyl ether compounds, crude polyalkylene glycol compounds, crude polyol ester compounds, crude cyclic polyether compounds, and crude carbonate compounds. The lubricating oil contains the high-purity oxygenic compound obtained by the process.</p> |
