Manufacturing Quality Control of 3-OCTYLHEPTAMETHYLTRISILOXANE
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a transparent glass container and observe its color, transparency, and presence of suspended particles or precipitates under natural light. Typically a colorless to pale yellow clear liquid. |
| Density | Densimeter Method / Pycnometer Method | Measure the ratio of mass to volume of the sample at a standard temperature (e.g., 25°C) using a densimeter or pycnometer to assess purity and batch consistency. |
| Refractive Index | Abbe Refractometer Method | Measure the refractive index of the sample at a specified temperature (e.g., 20°C or 25°C) using an Abbe refractometer as an auxiliary indicator of purity and molecular structure. |
| Purity (Main Component Content) | Gas Chromatography (GC) | Use capillary column gas chromatography with a flame ionization detector (FID) to identify components by retention time and quantify the main component via peak area normalization or external standard method. |
| Volatile Content/Moisture | Karl Fischer Titration | A specialized method for determining trace moisture; used for precise control of residual water in organosiloxanes to ensure product stability. |
| Infrared Spectroscopy (Structural Confirmation) | Fourier Transform Infrared Spectroscopy (FTIR) | Perform infrared scanning of the sample and compare with reference spectra to confirm the presence of characteristic functional groups such as Si–O–Si, Si–CH₃, and C–H, verifying correct molecular structure. |
| Viscosity | Rotational Viscometer Method | Measure the kinematic viscosity of the fluid under constant temperature using a rotational viscometer to evaluate flow properties for process control. |
| Impurity Analysis | GC-MS or HPLC | Use gas chromatography-mass spectrometry (GC-MS) or high-performance liquid chromatography (HPLC) to perform qualitative and quantitative analysis of potential by-products or degradation impurities. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Measure mass changes of the sample under programmed temperature increase to evaluate decomposition temperature and weight loss behavior, assessing stability under high-temperature conditions. |
