Abstract
Method for obtaining salts of tetracycline, characterized in that an antibiotic with the calcium, basic, plumbose, sodium or potassium salt of an aromatic acid is reacted in the form of a free base or of an hydrochloride by an electrophilic addition of the sulphonic groups and carboxylic acids to the tertiary amine group of the different tetracycline derivatives to form the new organic-saline compounds that precipitate from their corresponding aqueous solutions.
