After a little experimentation I am curious.
In an attempt to remove some of the water I slowly warmed my sulphuric acid on a heat controlled hot plate at 250c.
The hotplate being set to 250c I very much doubt that the acid got up to that temperature in that time.
I have a IR thermometer on it way.
It was only there for an hour but as it cooled I covered it with a piece of plastic.
Coming back later there was indeed water condensed on the plastic.
My question is simple really
Has anyone tried heating sulphuric slowly to 300c.
By slowly I mean so that it never actually boils.
My thinking is that as the boiling point increases with the concentration and as the liquid gets close to it's boiling point the water will evaporate and the concentration will increase.
As the boiling point is 300c at 95% I am thinking that this could be a safe way to concentrate sulphuric acid.
Instead of trying to go all the way to 98% as many horror stories I have read here suggest it's not much of a clever idea![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Or is this idea just another one of my "Don't be an idiot Gregory" ideas?
