Determination of Synthetic Hydrocarbons in Hybrid Mineral Oil Lubricants.

摘要

An analytical gas chromatographic procedure has been developed to qualitatively and quantitatively detect polyalpha olefins such as oligomers of decene-1 in hybrid mineral oil lubricants. The polyalpha olefin synthetic hydrocarbons used in hybrid lubricants are narrow boiling compounds producing specific peaks as compared to the broad range gaussian type distribution of mineral oils. Difficult base line definition and undetectable components such as C60 oligomers produce errors which are acceptable even if larger than desired. (Author)
