Discussion Overview

The discussion revolves around sodium dodecylbenzene sulfonate, exploring its properties, uses, and chemical structure. Participants inquire about its classification and characteristics, with a focus on its role as a detergent and surfactant.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant asks for clarification on what sodium dodecylbenzene sulfonate is, suggesting it might be a pesticide.
  • Another participant proposes that it is a detergent, describing its structural components, including the benzene sulfonate and dodecyl group, and explaining its surfactant properties.
  • A participant mentions a related compound, TEA-dodecylbenzenesulfonate, found in shampoo, noting a substitution of tetraethylammonium for sodium.
  • One participant provides a CAS number for sodium dodecylbenzene sulfonate and shares its molecular formula, molecular weight, melting point, and solubility in water, reinforcing its classification as a detergent.
  • Another participant expresses difficulty finding information on the compound, while a later reply corrects this by providing specific search instructions.

Areas of Agreement / Disagreement

Participants generally agree on the classification of sodium dodecylbenzene sulfonate as a detergent and surfactant, but there is some uncertainty regarding its specific applications and the initial assumption of it being a pesticide.

Contextual Notes

Some limitations include the potential for confusion between different related compounds and the varying availability of information across different sources.

can some tell me what exactly it is?

like pesticide or something?

a littleabout the properties would be nice


thanks :D

Sounds like a detergent. Structually it's bezene sulfonate (-SOOOH) with a dodecyl group (12-C hydrocarbon) substitued somewhere. React it with a sodium base NaB, it forms a sodium sulfonate salt which looks very much like a commercial detergent. The Na+SOOO- end is ionic in character and interacts with water; the hydrocarbon end is very nonpolar and can mix with oils. It acts as kind of intermediate between the oil and water, allowing them to mix (surfactant).

I found a similar "TEA-dodecylbenzenesulfonate" in my shampoo, it's the same thing substituting TEA=tetraethylammonium (Et4N+) (I think?) for sodium.
 
chemfinder don't got it
is not found ne where =(
