1 S is burned to produce SO2, converted to SO3, and reacts with HCl to yield HSO3CL. 2 The process is feasible, but unprofitable.
Our company has stopped producing chlorosulfonic acid for almost 12 months now
We mainly focus on using up the by-produced hydrogen chloride; we don’t care much about profits, as long as we don’t incur losses.
""\"Sulfur used to produce sulfur trichloride\" – what the heck is sulfur trichloride? How is it produced? It’s probably sulfur trioxide! Hehe
I’m sorry for mistyping ‘oxygen’ as ‘chlorine’; please forgive me, fellow sailors. Thank you!
That is the production of sulfuric acid, which mainly involves three steps: gas generation (sulfur burning to produce sulfur dioxide), conversion (sulfur dioxide being converted into sulfur trioxide), and absorption (sulfur trioxide being absorbed by sulfuric acid)
Rather than consuming the by-product hydrogen chloride, it is better to produce calcium chloride and polyaluminum chloride. Chlorosulfonic acid is a niche product, and its storage and sales are subject to numerous restrictions
