Industrial Applications of 18880-36-9
| Industry | Application | Process |
|---|---|---|
| Rubber Industry | Used as a vulcanizing agent in rubber product manufacturing to enhance heat resistance, abrasion resistance, and aging resistance | Added during rubber compounding and uniformly mixed with other additives prior to vulcanization |
| Pesticide Manufacturing | Used as a pesticide intermediate in the synthesis of specific pesticide types | Converted via chemical reaction into part of the target pesticide molecule |
| Chemical Feedstock | Used as a key reagent or catalyst in organic synthesis for producing other chemicals | Incorporated into various organic reactions—including addition and substitution—depending on the desired product |
| Dyeing and Printing Industry | Potentially used as a dye fixative or specialty finishing agent | Typically added in the later stage of dyeing and printing to fix color or achieve special textural effects |
| Petrochemical Industry | Acts as an auxiliary agent in certain petroleum product refining processes, such as fuel oil quality improvement | Used as an additive, incorporated during final blending to optimize product properties |
Manufacturing Quality Control of 18880-36-9
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 210-230 nm, calibrated against certified reference standard. |
| Moisture Content | Karl Fischer Titration | Coulometric or volumetric titration based on the reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Direct measurement using calibrated glass electrode in a 1% w/v aqueous solution at 25 C. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion; detection based on atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separation on anion-exchange column with conductivity detection; quantified using external calibration with NaCl standard. |
| Sulfate Impurity | IC or Turbidimetry | For IC: anion separation with conductivity detection; for turbidimetry: precipitation as BaSO4 and measurement of light scattering. |
| Residue on Ignition | Gravimetric Analysis | Heating at 700-750 C to constant weight; residue mass expressed as percentage of original sample. |
| Iron (Fe) Content | AAS | Atomic absorption spectroscopy using air-acetylene flame and Fe-specific hollow cathode lamp. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of solid or solution under controlled lighting and against white background. |
| Solubility in Water | Qualitative Dissolution Test | Observation of complete dissolution in distilled water at 20-25 C with gentle agitation within 5 minutes. |
| Organic Volatile Impurities | GC-FID | Separation by capillary GC and detection via flame ionization; identified and quantified using retention time and calibration standards. |
| Microbial Limits | Membrane Filtration + Culture | Sample filtration through 0.45 um membrane, followed by incubation on appropriate agar media for aerobic bacteria and molds/yeasts. |
