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, ציפוי, rubber and other fields. בנוסף, pine oil can also be used as a cleaning agent and disinfectant, וכו.

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, לדוגמה, acid values can be measured by acid-base titration, viscosity can be measured by viscometer, density can be measured by hydrometer, וכו.

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

שיטת זיהוי
Specific detection methods can be selected according to criteria, כמו:

טוֹהַר: כרומטוגרפיית גז (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.

מקדם השבירה: can be measured using a refractometer.

נקודת רתיחה: can be measured using closed or open cup method.

Acid value: The acid value can be determined by titration.

צְמִיגוּת: can be measured using a viscometer.

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