Industrial Applications of Proxan sodium
| Industry | Application | Process |
|---|---|---|
| Mining | Used as a flotation collector for the concentration of sulfide ores, including copper, lead, and zinc ores | Hydrometallurgy/flotation process |
| Rubber Industry | Used as an accelerator in rubber vulcanization to enhance the vulcanization rate | Rubber compounding and vulcanization process |
| Chemical Synthesis | Used as an organic synthesis intermediate for the preparation of other xanthate compounds | Organic synthesis reaction |
| Agriculture | Partially employed as an auxiliary component in insecticides or herbicides (subject to regulatory restrictions) | Pesticide formulation processing |
| Wastewater Treatment | Used as a heavy metal precipitant for treating heavy metal–containing wastewater (e.g., copper, nickel) | Chemical precipitation process |
Manufacturing Quality Control of Proxan sodium
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and state (usually light yellow to yellow powder or granules) of the sample to determine whether it is uniform, free from impurities, or agglomerated. |
| Purity/Main Content | Iodometric Titration | Utilize a quantitative oxidation-reduction reaction between sodium isopropyl xanthate and iodine; calculate its effective content based on the volume of iodine standard solution consumed during titration. |
| Loss on Drying | Gravimetric Method (Oven Drying) | Dry at specified temperature (e.g., 105°C) until constant weight is achieved, then calculate the percentage of mass loss to evaluate moisture and volatile content. |
| pH Value | pH Meter Measurement | Prepare a water solution of certain concentration and directly measure the acidity or alkalinity using a calibrated pH meter, reflecting product stability and by-product conditions. |
| Free Alkali (e.g., NaOH) | Acid-Base Titration | Use phenolphthalein or methyl orange as an indicator with a standard acid solution to titrate free alkali, evaluating residual alkali levels from the production process. |
| Insoluble Matter | Gravimetric Method (Filtration + Drying and Weighing) | Dissolve the sample, filter, dry the residue, and weigh it to calculate the proportion of insoluble matter, indicating mechanical impurities or unreacted raw materials. |
| Heavy Metals (e.g., Pb, As, etc.) | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, use atomic absorption spectroscopy or inductively coupled plasma mass spectrometry to determine the residual amounts of specific heavy metal elements. |
| Moisture | Karl Fischer Method | Utilize Karl Fischer reagent that quantitatively reacts with water in the sample, determining the moisture content precisely through coulometric or volumetric titration methods. |
| Thermal Stability/Decomposition Temperature | Thermogravimetric Analysis (TGA) | Measure the mass change curve of the sample as a function of temperature under programmed heating to determine the onset temperature of thermal decomposition, assessing storage and transportation safety. |
| Infrared Spectral Identification | Fourier Transform Infrared Spectroscopy (FTIR) | Identify characteristic functional group absorption peaks (e.g., C=S, C-O-C, etc.) and compare them with standard spectra to confirm structural consistency. |
