07.08.2010· Heat bisulfate to get pyrosulfate, then heat boric oxide with pyrosulfate, and you can distill off SO3 at a surprisingly "not too hot" temperature, of around 300degC. leaving a borosulfate mess behind. that was my invention anyway. Maybe if I had lived 120 years ago, they'd be producing sulfuric acid a different way now.

In the HF process, after the sulfuric acid and milled fluorspar are kneaded together, it is necessary to heat the mixture to vaporize the HF, leaving the dry gypsum residue. The reaction of sulfuric acid with limestone is highly exothermic, producing far more heat than that required to vaporize the O>2.
