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, patong na patong, rubber and other fields. Bukod pa rito, pine oil can also be used as a cleaning agent and disinfectant, atbp.

Main performance
The main properties of pine oil are shown in the following table:

These properties can be tested by different chemical analysis methods, physical tests and instrumental tests, halimbawa na lang, acid values can be measured by acid-base titration, viscosity can be measured by viscometer, density can be measured by hydrometer, atbp.

Relevant standards
The following are some properties and related criteria that pine oil may need to be tested for:

Test index and test method of pine oil

Paraan ng pagtuklas
Specific detection methods can be selected according to criteria, tulad ng:

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.

Index ng refractive: can be measured using a refractometer.

Punto ng flash: can be measured using closed or open cup method.

Halaga ng acid: The acid value can be determined by titration.

Lagkit: can be measured using a viscometer.

Moisture: Halide titration, Coulomb method and other methods can be used to determine moisture content.
