Is sulfation same as sulfonation?
Is sulfation same as sulfonation?
Sulfonation and sulfation are two important chemical processes used in many industries to add a sulfur-containing group to an organic compound. The main difference between sulfonation and sulfation is that sulfonation involves the formation of a C-S bond whereas sulfation involves the formation of a C-O-S bond.
What is the process of sulfonation?
Important sulfonation procedures include the reaction of aromatic hydrocarbons with sulfuric acid, sulfur trioxide, or chlorosulfuric acid; the reaction of organic halogen compounds with inorganic sulfites; and the oxidation of certain classes of organic sulfur compounds, particularly thiols or disulfides.
What is sulfonation reaction?
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.
What is oleum formula?
H2S2O7
Disulfuric acid/Formula
What is the purpose of sulfonation sulfation?
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.
Which Sulfonating agent is most efficient?
Sulfuric acid
Sulfuric acid, which may be considered as the SO,-H,O system, is a sulfonating agent employed most frequently.
Is sulfonation exothermic?
The liberated HCl gas is absorbed into water to make a dilute HCl solution. In operation, the alcohol or ethoxy alcohol feedstock is charged to the reactor and chlorosulfuric acid is gradually added. A good refrigeration system is required for heat removal because the reaction is exothermic.
What is the symbol of oleum?

Why oleum is called fuming h2so4?
When Oleum comes into contact with air following a spill, it releases Sulfur Trioxide. Because of the tendency to liberate Sulfur Trioxide on contact with air, Oleum is also known as “fuming Sulfuric Acid”.
What is meant by sulfonation?
(chemistry) The replacement of a hydrogen atom of an organic compound with a sulfonic acid (-SO3H) functional group, often by reaction with sulfuric acid at high temperatures.
What kind of bond is formed in a sulfonation reaction?
Sulfonation reactions form a C-S bond between one of the carbon atoms of the organic compound and the sulfur atom of the sulfur-containing compound. The final compound is an acidic compound and is categorized as a sulfonic acid. After the production, sulfonic acids can be isolated and stored due to their stability.
What happens when sulfur trioxide reacts with an organic molecule?
Sulfur trioxide (SO3) reacts with an organic molecule – in this case an alkyl benzene – to form a sulfur-carbon bond. One of the characteristics of this process is that the resultant alkyl benzene sulfonic acid is a stable molecule.
Why is sulfonation used on an industrial scale?
Sulfonation reaction is very difficult to be used in industrial scale because it is a very rapid and extreme exothermic reaction. Most organic compounds form a black char when contacted with sulfur trioxide due to this rapid reaction and heat formation.
Which is the final product of the sulfonation process?
Sulfonation is the process of directly attaching the sulfonic acid group, –SO 3 H, to carbon in an organic compound. The final product of the Sulfonation process is called the sulfonate.
