A small question about steaming acid
Thread Content
The purity of the sulfuric acid is 30%; I plan to purify it. Since its boiling point is around 330 degrees, can I raise the temperature to 120 degrees to evaporate the water? If the purity of the remaining sulfuric acid reaches 80%, I will be able to use it again. Will it work? I would appreciate the teacher’s guidance; if that’s not possible, could you suggest a solution to address the purity issue?
This should work; a small amount can be used in the laboratory. For industrial use, distillation equipment is problematic due to the high corrosivity.
Agree with the person above; it’s too corrosive, and equipment maintenance and updates are **a hassle**.
Reply 1# sdgm0010: If it is just sulfuric acid, heating and distillation can be carried out using quartz glass. The principle is the same as that of sulfuric acid used as a reagent; the key is to control the temperature.
:)I’ve learned it~ but I still feel like something is missing~
There are now complete sets of sulfuric acid concentration technologies; it is not difficult to reach 80% concentration. However, to achieve 80% concentration, the temperature needs to be increased significantly, which requires changing the material used. A 30% mutual extraction rate of 80% can be achieved using graphite heat exchangers and enamel towers.
