2-hydroxyethyl-n-octylsulfonic acid (CAS 3547-33-9), as a long-chain sulfonic acid derivative, has potential applications focusing on surfactants, industrial emulsification and organic synthesis fields. Its performance lies between that of short-chain sulfonic acids (such as hydroxyethyl sulfonic acid) and traditional alkylbenzene sulfonates, and it may possess both high emulsifying power and mildness.
Notes
Specific physical property parameters (melting point, boiling point, etc.) need to be determined experimentally.
Ecological toxicity should be evaluated before application (especially in aquatic environments);
The synthetic pathway may involve the reaction of ethylene oxide with octanol, followed by oxidative sulfonation (similar to the preparation method of hydroxyethyl sulfonic acid).
Surfactant
Due to the simultaneous presence of hydrophilic sulfonic acid groups and hydrophobic alkyl chains, it is suitable for:
Detergent: As a decontamination component, it reduces the surface tension of water and enhances the emulsification of oils.
Personal care products: Foaming agent in facial cleansers and shampoos, gentle cleansing (similar to the use of hydroxyethyl sulfonate).
Industrial additives
Emulsifier: Used in emulsion polymerization (such as styrene-acrylic emulsion, acrylic resin synthesis);
Electroplating additive: Improves the uniformity of metal coatings (refer to the electroplating application of hydroxyethyl sulfonic acid).
Organic synthesis intermediates
Sulfonic acid groups can participate in esterification and amidation reactions and be used to synthesize customized surfactants or functional molecules.
Potential risks (refer to the commonalities of sulfonic acid compounds)
Corrosiveness: Strong acidity may irritate the skin and eyes (rinse immediately after contact).
Environmental toxicity: The long carbon chain structure may have cumulative toxicity to aquatic organisms, and leakage prevention is required.
Protective measures
Operating requirements: Ventilated environment, wear anti-corrosion gloves, goggles and protective clothing;
Storage: Keep in a cool and dry place, away from oxidants/alkalis.
