Industrial Applications of 696-71-9
| Industry | Application | Process |
|---|---|---|
| Fragrance Industry | Used as a fragrance fixative, imparting floral, woody, and amber notes | Directly incorporated into fragrance formulations or converted via esterification to produce cyclooctanol-based fragrance esters |
| Organic Synthesis | Raw material for synthesizing intermediates such as cyclooctanone, cyclooctanoic acid, and cyclooctadiene | Converted through oxidation, dehydrogenation, or catalytic dehydration reactions |
| Plastics Industry | Co-component or modifier in plasticizers for polyvinyl chloride (PVC) | Blended with phthalate plasticizers to enhance low-temperature flexibility and compatibility |
| Pharmaceutical Industry | Intermediate in the synthesis of certain prostaglandin-based drugs and anti-inflammatory compounds | Incorporated into drug molecule construction via multi-step functional group transformations |
| Surfactants | Hydrophobic moiety for synthesizing nonionic surfactants (e.g., cyclooctanol ethoxylates) | Reacted with ethylene oxide (ethoxylation) |
Manufacturing Quality Control of 696-71-9
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (Assay) | Gas Chromatography (GC) with FID detector | Quantifies环辛醇 content by separation and flame ionization detection relative to internal/external standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine-sulfur dioxide reaction in pyridine/methanol medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Evaluates yellowness by matching sample color to APHA platinum-cobalt standards or measuring absorbance at 455 nm. |
| Density at 20 degC | Digital Density Meter or Pycnometer | Measures mass per unit volume using oscillating U-tube principle or calibrated glass pycnometer. |
| Refractive Index at 20 degC | Refractometer | Determines ratio of light velocity in air vs. sample using total internal reflection at prism-sample interface. |
| Non-Volatile Residue | Gravimetric Analysis after Evaporation | Quantifies residue by evaporating known sample mass under controlled conditions and weighing the dry residue. |
| Aldehyde Content | Spectrophotometry after reaction with Nash reagent | Measures aldehydes via formation of yellow chromophore (diacetylmonoxime) under acidic heating, measured at ~412 nm. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring atomic absorption of ground-state metal atoms in flame/graphite furnace. |
| Residue on Ignition | Gravimetric Analysis after Ashing | Determines inorganic ash content by ignition of residue from evaporation at 700-800 degC and weighing. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and quantifies chloride ions using ion-exchange column with conductivity detection, or titrates with silver nitrate using chloride-selective electrode. |
| Peroxide Value | Iodometric Titration | Measures hydroperoxides by oxidation of iodide to iodine under acidic conditions, followed by thiosulfate titration. |
