referencing Chromics HCL post (476334) and V. Verdsegast there as well concerning HCL in place of sulfuric, they used an alcohol solvent with the glycol, then H2O with the HCL.
The question is, what ratio of alcohol/water/acid is appropritate? That is, how is the amount of solvent determined in each case, a molar ratio? But when scaling up, is it correct to increse the solvent quantity accordingly, or use a lessor amount?
Thanks for any reference
