Индекс испитивања и метода испитивања боровог уља
Борово уље је природно смолно уље које се екстрахује из борова, такође се назива ретинол. Има добру растворљивост, viscosity and stability, and is often used in paint, coating, rubber and other fields. Додатно, pine oil can also be used as a cleaning agent and disinfectant, итд.
Main performance
The main properties of pine oil are shown in the following table:
| Перформансе | Index of detection |
|---|---|
| Exterior appearance | Color, transparency |
| Acid number | Mg KOH/g |
| Степен вискозности | millisecond |
| Степен растворљивости | Solubility in different solvents |
| Густина густине | G/ml |
These properties can be tested by different chemical analysis methods, physical tests and instrumental tests, на пример, acid values can be measured by acid-base titration, viscosity can be measured by viscometer, density can be measured by hydrometer, итд.

Метода детекције
Specific detection methods can be selected according to criteria, као такав:
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.
Релативна густина: 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.
Вискозност: can be measured using a viscometer.
Moisture: Halide titration, Coulomb method and other methods can be used to determine moisture content.
