Industrial Applications of DODECYLBENZENESULFONIC ACID
| Industry | Application | Process |
|---|---|---|
| Detergents | Anionic surfactant for laundry powders, liquid detergents, etc. | Used as primary surfactant or co-formulant; sodium salt obtained via sulfonation and neutralization is incorporated into final formulations |
| Petroleum extraction | Crude oil demulsifier, enhanced oil recovery (EOR) agent | Formulated with other surfactants for dehydration of produced fluids and improved crude oil recovery |
| Textile dyeing and finishing | Wetting agent, penetrating agent, leveling agent | Applied during dyeing and finishing processes via pad-dry or immersion methods |
| Metalworking | Component of metal cleaners | Acts as active ingredient in aqueous cleaning formulations to remove oils and greases from metal surfaces; typically co-formulated with other auxiliaries |
| Pesticides | Emulsifier, dispersant | Used in formulation of emulsifiable concentrates (EC), water emulsions (EW), and other agrochemical preparations to enhance stability of active ingredients via emulsification and dispersion |
Manufacturing Quality Control of DODECYLBENZENESULFONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Acid Value | Acid-Base Titration | Neutralization of sulfonic acid groups with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| Active Matter Content | Two-Phase Titration (Scholander method) | Extraction and titration of active surfactant in chloroform/water system using cetylpyridinium chloride as titrant. |
| Sulfur Content | Combustion IC | High-temperature combustion followed by ion chromatographic quantification of sulfate ions. |
| Water Content | Karl Fischer Titration | Electrochemical titration based on the reaction of iodine with water in methanol/pyridine medium. |
| Color (APHA) | Visual or Instrumental Comparison | Comparison of sample color against platinum-cobalt standard solutions using APHA scale. |
| pH (1% aqueous solution) | pH Meter Measurement | Direct measurement of hydrogen ion activity in a 1% w/w aqueous solution at 25 C. |
| Free Sulfuric Acid | Acid-Base Titration | Selective titration of residual H2SO4 after precipitation of sulfonate salts, using methyl orange indicator. |
| Heavy Metals (as Pb) | AAS | Atomic absorption spectroscopy after wet ashing and acid digestion, measuring absorbance at characteristic wavelengths. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after high-temperature incineration at 500-600 C. |
| Surfactant Purity (by HPLC) | Reversed-Phase HPLC | Separation on C18 column with UV detection at 210 nm; quantification against reference standard. |
| Odor | Sensory Evaluation | Assessment by trained personnel against defined odor standards (e.g., mild hydrocarbon-like). |
| Viscosity (at 25 C) | Rotational Viscometry | Measurement of resistance to flow under controlled shear rate using calibrated rotational viscometer. |
