sulfonic acid for boiler cleaning

Sulfonic acid can be mistaken for sulfuric acid, as only one group of hydroxyl is replaced by an organic substituent. But this is actually produced through sulfonation with the use of an agent called sulfur trioxide. Sulfonic acid is a very strong acid and may produce strong corrosive effects. Free Chat
