- Phenol structure Calculated based on the peaks derived from methine hydrogen at the 2- and 6-positions of the aromatic ring appearing around 8.0 ppm.
- Table 2 shows the compositions of the ester compounds contained in the lubricating oil base oils according to Examples 1 to 8 and Comparative Examples 1 to 3 obtained by measurement.
- the kinematic viscosities of the lubricating oil base oils according to the Examples and Comparative Examples were 40 ° C. kinematic viscosities and 40 ° C. kinematic viscosities by a Stavinger kinematic viscometer (trade name: SVM3000, manufactured by Antonio Par) satisfying the accuracy required by ATM D7042. It was evaluated by measuring 100 ° C. kinematic viscosity (mm 2 / s). The lower the viscosity, the better the low torque property.
