Standard Test Method for Methyl Hydrogen Content of Hydrocarbon Oils by High Resolution Nuclear Magnetic Resonance Spectroscopy

Importancia y uso:

5.1 Methyl hydrogen content is a key characteristic of hydrocarbon lubricating oils and can affect a variety of properties of the oil including its boiling range, viscosity, low temperature flow, and oxidation stability.

5.2 The NMR procedure does not require calibration standards of known methyl hydrogen content and is applicable to a wide range of hydrocarbon lubricating oils that are completely soluble in chloroform at ambient temperature.
