Abstract

Preparation process of the tetracycline alcohol sulphates whose alkyl radical comprises at most 4 carbon atoms, characterized by contacting an ion-exchange resin of the cationic type with an alkali alcohol sulphate in solution in isopropanol, said alcohol sulfate comprising at most 4 atoms of carbon, then the sulfuric acid thus obtained is made to act on tetracycline base in isopropanol medium, the products are then left in contact with stirring and finally the tetracycline alcohol sulphate formed in solution is isolated by drying the solvent or addition precipitation to the reaction medium of a liquid in which the desired product is insoluble.
