A 13C-NMR-BASED COMPOSITION OF HIGH QUALITY LUBE BASE OILS AND A METHOD TO ENABLE THEIR DESIGN AND PRODUCTION AND THEIR PERFORMANCE IN FINISHED LUBRICANTS

摘要

A lubricant base oil is provided. The lubricant base oil has a low temperature property determined using a stepwise regression of carbon-13 nuclear magnetic resonance (NMR) spectroscopy peak values. A method of selecting candidate lubricant base oils, or mixtures thereof, having acceptable low temperature performance is also provided. An online method of blending a lubricant base oil and a finished lubricant are also provided.
