Meaning and Definition
The chemical process of introducing a sulfonic acid group (-SO₃H) into an organic molecule.
A key industrial reaction used in the production of detergents, dyes, pharmaceuticals, and other specialty chemicals, involving the attachment of a sulfonyl functional group.
Dialectal Variation
British vs American Usage
Differences
The spelling 'sulphonation' is the standard British English variant, while 'sulfonation' is standard in American English. The chemical process and meaning are identical.
Connotations
None beyond the spelling difference. The term is purely technical.

Common Mistakes When Using “sulfonation”
- Misspelling as 'sulphonization' or 'sulfonization'.
- Confusing it with 'sulfation' (addition of sulfate, SO₄²⁻).
- Using it as a verb in place of 'sulfonate' (e.g., 'They will sulfonation the compound' is incorrect).
FAQ
Frequently Asked Questions
No. Sulfonation introduces a sulfonic acid group (-SO₃H). Sulfation introduces a sulfate group (-OSO₃⁻ or SO₄²⁻). They are distinct chemical processes.
Concentrated or fuming sulfuric acid (oleum, which contains sulfur trioxide, SO₃) is the most classic reagent for sulfonation reactions.
The detergent industry. Sulfonation of linear alkylbenzenes produces linear alkylbenzene sulfonates (LAS), which are major anionic surfactants in household and industrial cleaners.
Yes, through a process called desulfonation. Heating an aromatic sulfonic acid with dilute acid or steam under pressure can remove the sulfonic acid group, which is useful in synthetic chemistry for directing substitutions.
The chemical process of introducing a sulfonic acid group (-SO₃H) into an organic molecule.
Sulfonation is usually technical/scientific in register.
Sulfonation: in British English it is pronounced /ˌsʌlfəˈneɪʃən/, and in American English it is pronounced /ˌsʌlfəˈneɪʃən/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: 'SULfur' is added in a 'FONAtion' (formation) reaction to create a sulfonate.
Conceptual Metaphor
A CHEMICAL PROCESS IS A JOURNEY (The molecule undergoes sulfonation to reach its final, more useful state).
