Abstract
The pressure coefficients of viscosity of hydrocarbons and ethers containing two to four phenyl groups linked either directly, via methylene bridges, or via CH(CH3) bridges, were studied with a view to elucidating the reason for the extreme viscosity‐pressure behavior of certain mineral oils. Measurements were made in the range of 1 to 2000 atm at 25, 40, 60, and 80 °C. The results show the existence of a simple relationship between molecular structure and viscosity‐pressure coefficient, and suggest applications in control engineering and lubrication technology.Keywords
