Abstract: A method for the manufacture of highly purified 68Ge material for radiopharmaceutical purposes. The invention particularly concerns the production of 68Ge-API (API=Active Pharmaceutical Ingredient) solution complying with the Guidelines for good manufacturing practices (GMP). Starting material for the method of the present invention can be a 68Ge stock solution of commercial or other origin as raw material. Such 68Ge containing raw solutions are purified from potential metal and organic impurities originating from production processes. The radiochemical method disclosed is based on a twofold separation of 68Ge from organic and metallic impurities with two different adsorbent materials. During the first separation phase 68Ge is purified from both organic and metallic impurities by adsorption in germanium tetrachloride form, after which hydrolyzed 68Ge is purified from remaining metallic impurities by cation exchange. The final 68Ge-API-product e.g.

Abstract: The invention pertains to a process for converting a feedstock comprising cyclic alkyleneureas into their corresponding alkyleneamines, comprising —a CO2 removal step in which cyclic alkyleneureas are converted into their corresponding alkyleneamines by reacting cyclic alkyleneureas in the liquid phase with water with removal of CO2, —an amine removal step wherein cyclic alkyleneureas are converted in a reactive separation process into their corresponding alkyleneamines by reaction with an amine compound selected from the group of primary amines or secondary amines which have a higher boiling point than the alkyleneamines formed during the process. It has been found that the combination of a CO2 removal step and an amine removal step makes it possible to convert alkyleneureas into the corresponding amines in an efficient manner in a high reaction rate.
