Is chlorosulfonic acid a strong acid?
Is chlorosulfonic acid a strong acid?
CHLOROSULFONIC ACID is a strong oxidizing acid. Reacts violently with water, strong mineral acids and bases, alcohols, finely dispersed organic matter.
How is chlorosulfonic acid made?
Synthesis. The industrial synthesis entails the reaction of hydrogen chloride with a solution of sulfur trioxide in sulfuric acid: HCl + SO3 → ClSO3H.

What precautions should be taken while handling chlorosulfonic acid?
All persons handling chlorosulfonic acid should exercise care to prevent contact with skin, eyes or clothing and to prevent breathing of mists or vapors. Use with adequate ventilation and wash hands thoroughly after handling.
Why is chlorosulfonic acid used in organic synthesis?
It reacts violently with water evolving heat and large quantities of white fumes of hydrochloric and sulfuric acid. The uses are principally in organic synthesis as a sulfating, sulfonating or chlorosulfonating agent. It is preferred in many applications because it is a strong agent that is less destructive than sulfur trioxide.
What happens if you get in contact with chlorosulfonic acid?
Chlorosulfonic acid is a strong acid and powerful desiccant. Skin or eye contact with the liquid acid will cause severe chemical burns. Prolonged skin contact may cause corrosion with pain, ulcerations, blisters or peeling of skin. Prolonged eye contact may cause corrosion, redness or swelling.
What are the physical properties of chlorosulfonic acid?
Physical Properties Chlorosulfonic acid has a strong, irritating, acrid odor and is very hydroscopic. CSA reacts violently with water, so uncontrolled contact with aqueous systems should be avoided.
How is chlorosulfuric acid prepared in a laboratory?
It can also be prepared by chlorination of sulfuric acid, written here for pedagogical purposes as HSO 3 (OH), vs. the usual format H 2 SO 4 : The latter method is more suited for laboratory-scale operations. ClSO 2 OH is used to prepare alkyl sulfates, which are useful as detergents and as chemical intermediates:
