Abstract
New procedure for obtaining a stable salt of penicillin characterized essentially because an ordinary solution of penicillin is associated by mixing with a solution of bis (phenylmethyllamino) ethane dihydrochloride, taking care that the latter has a concentration that at the temperature to be worked does not exceed its own solubility factor that the concentration of penicillin is such that when bound to the solution of bis (phenylmethyleneamino) ethane dihydrochloride, it exceeds the solubility factor of the whole at the temperature being worked and that at the ph of the solution is between two maximum and minimum levels so that it is not so high that it releases the bis (phenylmethyleneamino) ethane as a free base or so low that it inactivates or simply precipitates penicillin.
