松油是从松树中提取的天然树脂油, 也称为视黄醇. 它具有良好的溶解性, viscosity and stability, and is often used in paint, 涂层, rubber and other fields. 此外, pine oil can also be used as a cleaning agent and disinfectant, ETC.

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, 例如, acid values can be measured by acid-base titration, viscosity can be measured by viscometer, density can be measured by hydrometer, ETC.

检测方法
Specific detection methods can be selected according to criteria, 例如:

纯度: 气相色谱法 (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.

相对密度: can be measured using equipment such as a densitometer or a specific gravity bottle.

折射率: can be measured using a refractometer.

闪点: can be measured using closed or open cup method.

酸价: The acid value can be determined by titration.

粘度: can be measured using a viscometer.

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