Сосновое масло – это натуральное смолистое масло, добываемое из сосновых деревьев., также называется ретинолом. Имеет хорошую растворимость, viscosity and stability, and is often used in paint, покрытие, rubber and other fields. Кроме того, pine oil can also be used as a cleaning agent and disinfectant, и т. д..

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, например, acid values can be measured by acid-base titration, viscosity can be measured by viscometer, density can be measured by hydrometer, и т. д..

Метод обнаружения
Specific detection methods can be selected according to criteria, такой как:

Чистота: Газовая хроматография (ГК) can be used to detect the content of various chemical components in pine oil, or infrared spectroscopy (IR) can be used to detect purity.

Относительная плотность: can be measured using equipment such as a densitometer or a specific gravity bottle.

Показатель преломления: can be measured using a refractometer.

точка возгорания: can be measured using closed or open cup method.

Кислотное число: The acid value can be determined by titration.

Вязкость: can be measured using a viscometer.

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