1. There are two methods for moisture detection: Karl Fischer method and azeotropic distillation method.
2. Determination of distillation range, measure the distillation temperature when it reaches the specified distillation temperature, and measure the distillation amount when it reaches the specified distillation temperature
3. Determination of viscosity
4. Determination of flash point
5. Determination of ignition point
6. Determination of nitrogen and salt content
