Proposed Standard will Help Determine Methyl Hydrogen Content Standard in Hydrocarbon Oils

Translations

A proposed ASTM International standard will be used to determine the total methyl hydrogen content of un-additized base stock hydrocarbon oils (lubricating oils). The test method uses high resolution nuclear magnetic resonance (NMR) spectrometers on samples that are completely soluble in chloroform at ambient temperature. ASTM’s petroleum products, liquid fuels, and lubricants (D02) is developing the proposed standard.

“Methyl hydrogen content is a key compositional 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,” says ASTM International member Frank Di Sanzo, a distinguished research associate at ExxonMobil Research and Engineering.

According to Di Sanzo, the proposed standard (WK73554) will continuously improve the approach of using compositional chemistry for determining the effects on lubricating oils.

ASTM welcomes participation in the development of its standards. Become a member at www.astm.org/JOIN.
