Industrial Applications of Butyl disulfide
| Industry | Application | Process |
|---|---|---|
| Rubber Industry | Vulcanization accelerator, antioxidant | Blended with rubber during compounding and participates in vulcanization to enhance the physical properties and aging resistance of vulcanized rubber |
| Lubricating Oil Additives | Extreme pressure/anti-wear agent, antioxidant | Added to mineral or synthetic lubricating oils; forms a sulfide protective film on metal surfaces to improve load-carrying capacity and reduce wear |
| Pesticide Intermediates | Raw material for organosulfur fungicides and insecticides | Used in the synthesis of sulfur-containing pesticides, such as dithiocarbamate fungicides (e.g., mancozeb) |
| Organic Synthesis | Organosulfur reagent, sulfiding agent | Serves as a sulfur source in organic synthesis to construct C–S bonds or prepare other organosulfur compounds |
Manufacturing Quality Control of Butyl disulfide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard under validated chromatographic conditions. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acidity (as H₂S or acidic impurities) | Acid-Base Titration with standardized NaOH and potentiometric endpoint detection | Neutralization of acidic species using sodium hydroxide; equivalence point determined by pH electrode. |
| Residue on Evaporation | Gravimetric Analysis (Weight Loss on Drying) | Sample evaporated to dryness under controlled temperature and pressure; non-volatile residue weighed after cooling in desiccator. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma–Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of metals in high-temperature plasma; quantification via element-specific emission line intensities. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Measurement of absorbance at 430 nm in a 10-cm cell relative to platinum-cobalt standards; reported as APHA units. |
| Density at 20 °C | Digital Density Meter (Oscillating U-tube principle) | Determination of density from the resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 °C | Abbe Refractometer | Measurement of angle of refraction of monochromatic light (sodium D-line) passing through sample at controlled temperature. |
| Sulfur Content | Combustion IC (Ion Chromatography after oxidative combustion) | Oxidative combustion converts organic sulfur to sulfate; sulfate quantified by suppressed conductivity detection in IC. |
| Volatile Impurities (e.g., dibutyl sulfide, butanethiol) | Gas Chromatography–Mass Spectrometry (GC-MS) | Separation by GC followed by electron ionization and mass spectral identification/quantification of volatile impurities. |
| Non-Volatile Residue (NVR) | Gravimetric Analysis after Solvent Extraction and Evaporation | Extraction with specified solvent (e.g., toluene), filtration, evaporation, and weighing of residual solids. |
| Odor Threshold (Qualitative Assessment) | Sensory Evaluation by Trained Panel | Comparative assessment against reference standards under controlled conditions to detect off-odor intensity and character. |
| Viscosity at 25 °C | Rotational Viscometer (e.g., spindle-type) | Measurement of torque required to rotate a spindle at fixed speed in sample, converted to dynamic viscosity (cP). |
