Dodecylbenzenesulphonic Acid CAS 27176-87-0

1. Dodecylbenzenesulphonic acid (DBSA) CAS 27176-87-0 is a linear alkylbenzene sulfonic acid (LABSA) primarily used as a key raw material and surfactant intermediate in the manufacture of household, institutional, and industrial detergents, including laundry, dishwash, and hard surface cleaners .
2. Dodecylbenzenesulphonic acid is utilized as an effective emulsifier, wetting agent, and foaming agent, and can be neutralized with various bases and amines to produce a wide range of sulfonates for different formulations .
3. Dodecylbenzenesulphonic acid is employed in industrial applications such as a promoter in the production of overbased calcium sulfonate grease, a component in acidic cleaning products, and in enhanced oil recovery as a drilling fluid additive .
4. Researchers Dodecylbenzenesulphonic acid and formulators use DBSA in the synthesis of conductive polymers like polyaniline, as a catalyst for esterification reactions in biodiesel production, and as a versatile building block in organic and pharmaceutical synthesis .

1. Dodecylbenzenesulphonic acid CAS 27176-87-0 must be stored in a tightly sealed container in a cool, dry, and well-ventilated area, away from heat, sparks, and open flames, with recommended storage in a cool, dark place (<15°C) and protected from metals .
2. Dodecylbenzenesulphonic acid is classified as a corrosive and hazardous substance with GHS signal word "Danger" and hazard statements including H314 (Causes severe skin burns and eye damage), H302 (Harmful if swallowed), H318 (Causes serious eye damage), and H410 (Very toxic to aquatic life with long lasting effects) .
3. Personnel must wear chemical-resistant gloves, eye protection, face protection, and protective clothing when handling this substance, ensuring adequate ventilation and avoiding breathing mists or vapors .
4. Keep Dodecylbenzenesulphonic acid away from incompatible materials such as strong oxidizing agents, strong bases, and metals (it attacks many metals); store locked up and follow precautionary statements including P260, P280, P305+P351+P338, P310, and P391 .

1. Isolate the spill area immediately, ensure adequate ventilation, remove all sources of ignition, and wear full personal protective equipment including chemical protection suit and self-contained breathing apparatus when dodecylbenzenesulphonic acid is released .
2. Collect leaking liquid in sealable, non-metallic containers; cautiously neutralize residues with sodium bicarbonate, lime, or soda ash, and use non-sparking tools for cleanup .
3. Avoid Dodecylbenzenesulphonic acid creating vapors or mists during cleanup to prevent respiratory exposure; do NOT let the chemical enter drains or water courses as it is very toxic to aquatic life with long-lasting effects .
4. Dispose of collected material as hazardous waste according to local, state, and federal environmental regulations in an approved waste disposal plant; for large spills, dike far ahead to contain for later disposal .

1. Dodecylbenzenesulphonic acid CAS 27176-87-0 is combustible with a flash point ranging from 85°F (29°C) to 211°C depending on the form and source; vapors may form explosive mixtures with air, and containers may explode when heated .
2. Use Dodecylbenzenesulphonic acid dry chemical powder, carbon dioxide, alcohol-resistant foam, or water spray to extinguish fires; do NOT use a direct water jet as it may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning dodecylbenzenesulphonic acid .
4. Hazardous decomposition products formed under fire conditions include toxic and irritating fumes of sulfur oxides, nitrogen oxides, carbon monoxide, carbon dioxide, and hydrogen sulfide ; contain fire runoff to prevent environmental contamination and pollution .
