Pine oil is a natural resinous oil extracted from pine trees, also called retinol. It has good solubility, viscosity and stability, and is often used in paints, coatings, rubber and other fields. In addition, 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 table below:
| performance | Detection Indicator |
|---|---|
| Exterior | color, transparency |
| acid value | mgKOH/g |
| viscosity | millisecond |
| Solubility | Solubility in different solvents |
| density | g/ml |
These properties can be detected by different chemical analysis methods, physical tests and instrumental tests, for example, acid value can be measured by acid-base titration, viscosity can be measured by viscometer, density can be measured by hydrometer, etc.
Related standards
The following are some properties and related standards that may need to be tested for pine oil:
| performance | Related standards |
|---|---|
| purity | GB/T602-2007 |
| Relative density | GB/T 4472-2011 |
| Refractive index | GB/T6488-2008 |
| Flash point | GB/T 261-2008 |
| acid value | GB/T 5530-2014 |
| viscosity | GB/T 265-1988 |
| moisture | GB/T6283-2008 |
Detection method
The specific detection method can be selected according to the standard, for example:
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.
Relative Density: Can be measured using equipment such as a density meter or a pycnometer.
Refractive Index: Can be measured using a refractometer.
Flash Point: Can be measured using the closed cup method or the open cup method.
Acid Value: Acid value can be determined using titration.
Viscosity: It can be measured with a viscometer.
Moisture: Moisture content can be determined using methods such as halide titration, coulometric method, etc.
