Synthesis with H2S04 and CaCO3/CaO?

[ponellibro]

OK so now i have this last problem. my H2SO4 has only 15%...
So what can I do?
Can I boil the water away if i can't freeze it away?
Can I do smth else to get a higher concentration?
Or can i substitute the sulfuric acid with other acids? Citric acid f.e. is avaliable in high concentrations fluid or anhydrous...
Ordering higher concentrated H2SO4 is the last option!
Please help, I'm stuck

ponellibroGo to the hardware store and by drain cleaner like rooto liquid drain cleaner, it is 93% sulfuric acid.

just boil the water off under no circustance use the dilute 15% or loose everything into an aqueous solution that may beoe too acidic and hydrolyze your product, just listen to what we all say it's plain stupid to use dilute

I have some pharmagrade concentrated HCl (37%) left and I'm interessted in turning some base into Amph-HCL. Is it made like Sulfate (adding HCl dripwise) or by using gaseous HCl?

thx in advane

Mohammed_Leeit can be made both ways but it is hard to isolate and store, as opposed to methamphetamine it is more hygroscopic I heard
