Abstract
The present invention refers to a clavulanic acid recovering procedure without amines use, wherein clavulanic acid alkaline salts are precipitated in a extremely pure way, extracting a clavulanic acid organic solution with an alkali metal aqueous solution at a pH between 6.0 and 6.5 adding a lower alcohol to aqueous phase, and causing precipitation at low temperature by adding a solvent as isopropanol or ketone.
