What is sulfonation process?
Sulfonation is the term that identifies an electrophilic chemical reaction where a sulfonic group SO3H is incorporated into a molecule with the capacity to donate electrons. The product of this chemical reaction is recognized as sulfonic acid if the electron donor molecule is a carbon.
What is sulfonation reaction?
Sulphonation Reaction
The replacement of the hydrogen atom of an organic compound with sulfonic acid (-SO3H) functional group, often by the reaction with sulfuric acid at higher temperatures, is called Sulphonation. “The introduction of a sulfonic acid group into an aromatic compound is referred to as sulphonation.”
What is sulfonation of aromatic compounds?
Aromatic sulfonation is an organic reaction in which a hydrogen atom on an arene is replaced by a sulfonic acid functional group in an electrophilic aromatic substitution. Aryl sulfonic acids are used as detergents, dye, and drugs.
What is sulphonation Class 11?
Sulphonation of benzene is a process of heating benzene with fuming sulphuric acid (H 2SO 4 +SO 3) to produce benzenesulphonic acid. The reaction is reversible in nature.
What is sulphonation example?
Sulfonation is a reversible reaction that produces benzenesulfonic acid by adding sulfur trioxide and fuming sulfuric acid. The reaction is reversed by adding hot aqueous acid to benzenesulfonic acid to produce benzene.
Why is sulphonation important?
Sulfonation is a valuable chemical reaction used to prepare a wide range of sulfonic acid derivatives and sulfonyl chlorides. There are many sulfonic acids that have the general formula RSO3H, where R represents an organic substituent such as an alkyl or aryl group.
Which reagent is used for sulphonation?
Answer: fuming sulphuric acid is used as a reagent in sulphonation reaction. Explanation: Sulphonation:- Basically Sulfonation is a reaction of benzene with fuming sulphuric acid , in this process benzene is heated with fuming sulphuric acid that gives benzenesulfonic acid and the nature of this reaction is reversible.
Why sulphonation is reversible?
Sulfonation of benzene is a reversible reaction. Sulfur trioxide readily reacts with water to produce sulfuric acid and heat. Therefore, by adding heat to benzenesulfonic acid in diluted aqueous sulfuric acid the reaction is reversed.
What is sulfonation used for?
Sulfonation and sulfation are major industrial chemical processes used to make a diverse range of products, including dyes and color intensifiers, pigments, medicinals, pesticides and organic intermediates.
What is sulfonation chemistry?
Sulfonation: A chemical reaction which introduces the sulfonic acid functional group (-SO3H) into a molecule. Sulfonation with sulfur trioxide and sulfuric acid converts benzene into benzene sulfonic acid.
