Testindex und Testmethode von Kiefernöl

Kiefernöl ist ein natürliches Harzöl, das aus Kiefernbäumen gewonnen wird, auch Retinol genannt. Es hat eine gute Löslichkeit, viscosity and stability, and is often used in paint, Beschichtung, rubber and other fields. Zusätzlich, pine oil can also be used as a cleaning agent and disinfectant, usw.

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

LeistungErkennungsindex
Exterior appearanceFarbe, Transparenz
Acid numberMg KOH/g
Viskositätsgradmillisecond
Degree of solubilitySolubility in different solvents
Dichte der DichteG/ml

These properties can be tested by different chemical analysis methods, physical tests and instrumental tests, Zum Beispiel, acid values can be measured by acid-base titration, viscosity can be measured by viscometer, density can be measured by hydrometer, usw.

Nachweismethode
Specific detection methods can be selected according to criteria, wie zum Beispiel:

Reinheit: Gaschromatographie (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.

Brechungsindex: 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.

Viskosität: can be measured using a viscometer.

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