Industrial Applications of Dibenzyl sulphide
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as a pharmaceutical intermediate in the synthesis of antibacterial or antitumor agents | Reacted with benzyl halides via sulfidation |
| Agrochemicals | Used as a synthetic raw material for insecticides or fungicides | Condensed with other organic compounds under catalytic conditions |
| Rubber | Used as a vulcanization accelerator or crosslinking agent to enhance rubber elasticity and durability | Heated and reacted with other additives during rubber compounding |
| Organic Synthesis | Used as a thioether template for constructing complex molecular architectures | Functionalized via nucleophilic substitution or oxidation reactions |
| Materials Science | Used in the synthesis of sulfur-containing polymers or functional polymers | Coupled with other monomers through polymerization or graft modification |
| Fragrances | Used as an intermediate in the synthesis of certain sulfur-containing fragrance compounds (used within regulatory limits) | Molecular structure modified via esterification or reduction reactions |
Manufacturing Quality Control of Dibenzyl sulphide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantitative determination based on peak area comparison with a certified reference standard using a suitable capillary column and flame ionization detector. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium; endpoint detected amperometrically. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing at 700-800 C in a muffle furnace. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance of ground-state atoms in a graphite furnace or flame atomizer. |
| Chloride Impurity | Potentiometric Titration with Silver Nitrate | Titration using AgNO3 solution with silver electrode detection; chloride forms insoluble AgCl, causing potential shift at endpoint. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitation of sulfate as BaSO4 in acidic medium followed by filtration, drying, and weighing of the precipitate. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of free acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Comparison of sample color against platinum-cobalt standard solutions or measurement of absorbance at 455 nm in a 10 cm cell. |
| Density at 20 C | Digital Density Meter | Determination of mass per unit volume using oscillating U-tube principle calibrated with water and air standards. |
| Refractive Index at 20 C | Refractometry | Measurement of light bending angle at air-sample interface using Abbe refractometer or digital equivalent calibrated with distilled water. |
| Non-Volatile Residue | Evaporation and Weighing | Evaporation of a known mass of sample to dryness under controlled conditions, followed by cooling and gravimetric determination of residue. |
| Odor | Sensory Evaluation | Qualified personnel assess presence and intensity of characteristic odor against reference material under standardized conditions. |
