| Cleaning Products | Used as a cleaning agent component | Applied as a surfactant in formulations to aid soil removal |
Manufacturing Quality Control of Oleyl alcohol
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample color, transparency, and presence of suspended particles or precipitates in a transparent container to determine clarity and homogeneity. |
| Density | Densitometer / Digital Density Meter | Measure the mass per unit volume at a specified temperature (e.g., 20°C) to assess purity and compositional consistency. |
| Viscosity | Capillary Viscometer / Rotational Viscometer | Measure the flow resistance of the oil-alcohol mixture at a specific temperature (typically 40°C), which affects fuel atomization performance. |
| Acid Value (Acid Number) | Acid-Base Titration | Titrate free fatty acids in the sample with a standardized potassium hydroxide (KOH) ethanol solution; calculate the milligrams of KOH consumed per gram of sample (mg KOH/g). |
| Water Content | Karl Fischer Titration | Utilize the quantitative reaction between iodine and sulfur dioxide in a pyridine/methanol system with water to precisely determine trace moisture levels (ppm level). |
| Free Glycerol Content | Gas Chromatography (GC) or Spectrophotometry | Measure free glycerol concentration after derivatization via GC, or by enzymatic reaction followed by colorimetric analysis. |
| Total Glycerol (including bound glycerol) | Acid Hydrolysis + GC or Spectrophotometry | First hydrolyze the sample to release all glycerol, then measure total glycerol content to calculate conversion efficiency. |
| Fatty Acid Methyl Ester Composition | Gas Chromatography-Mass Spectrometry (GC-MS) | Convert the sample into methyl ester derivatives and analyze the types and relative contents of individual fatty acid components using GC-MS. |
| Ester Content | Proton Nuclear Magnetic Resonance (¹H-NMR) or GC | Calculate ester content based on characteristic peak areas in NMR, or determine total ester content via GC with internal standard method to reflect reaction completeness. |
| Flash Point | Closed Cup Method (e.g., Pensky-Martens) | Determine the lowest temperature at which the vapor-air mixture momentarily ignites upon exposure to a flame, evaluating safety during storage and transportation. |
| Sulfur Content | Ultraviolet Fluorescence or X-ray Fluorescence (XRF) | After combustion, measure SO₂ concentration via ultraviolet fluorescence; or use non-destructive XRF to directly measure sulfur element content. |
| Oxidation Stability | Accelerated Oxidation Method (Rancimat Method) | Expose the sample to air under elevated temperature and airflow; monitor conductivity changes and record the induction period (in hours) to evaluate antioxidant capacity. |
| Cold Filter Plugging Point (CFPP) | Cold Filter Plugging Point Apparatus | Simulate low-temperature conditions to determine the highest temperature at which the sample fails to pass through a filter under specified pressure, reflecting low-temperature flow properties. |
| Ash Content | Gravimetric Method (Ignition Residue) | Incinerate the sample at high temperature and weigh the residual inorganic material to assess inorganic impurity levels. |
| Copper Strip Corrosion | Copper Strip Corrosion Test | Immerse a clean copper strip into the sample and heat it under specified conditions; observe discoloration of the copper strip to determine the presence of corrosive substances. |
