Test index and test method of pine oil
Pine oil is a natural resin oil extracted from pine trees, also called retinol. It has good solubility, viscosity and stability, and is often used in paint, coating, rubber and other fields. In addition, pine oil can also be used as a cleaning agent and disinfectant, etc.
Main performance
The main properties of pine oil are shown in the following table:
Performance | Index of detection |
---|---|
Exterior appearance | Color, transparency |
Acid number | Mg KOH/g |
Degree of viscosity | millisecond |
Degree of solubility | Solubility in different solvents |
Density of density | G/ml |
These properties can be tested by different chemical analysis methods, physical tests and instrumental tests, for example, acid values can be measured by acid-base titration, viscosity can be measured by viscometer, density can be measured by hydrometer, etc.

Test index and test method of pine oil
Method of detection
Specific detection methods can be selected according to criteria, such as:
Purity: Gas chromatography (GC) can be used to detect the content of various chemical components in pine oil, or infrared spectroscopy (IR) can be used to detect purity.
Relative density: can be measured using equipment such as a densitometer or a specific gravity bottle.
Refractive index: can be measured using a refractometer.
Flash point: can be measured using closed or open cup method.
Acid value: The acid value can be determined by titration.
Viscosity: can be measured using a viscometer.
Moisture: Halide titration, Coulomb method and other methods can be used to determine moisture content.
