Abstract
A process for the preparation of diphenhydramine naphthalene disulfonate, which has very low solubility in water, is characterized by the steps of dissolving a disulfonated hydrocarbon of the general formula: ** (See formula) ** where "R" is a bivalent hydrocarbon radical, diphenhydramine salt (its hydrochloride) is placed in solution, bring both solutions to contact and cause as much precipitation as possible, stop, wash and dry the precipitate.
