In the chloromethylation procedure in TSII using a benzene, paraformaldehyde, toluene as the solvent, and hydrogen chloride gas, about how much H2SO4, HCl should go in the generator for, say, a 1 mole batch to be able to gas for 2-3 hrs?
From TFSE, Scooby said to drip the H2SO4 at a rate of two drops per second.. But SWIM isn't sure about the amounts of the acids to use.
