ABSTRACT:
This invention provides a method for synthesizing pure carboxyethyl germanium sesquioxide that does not include any toxic impurities, such as germanium dioxide or metallic germanium. Neither of these toxic compounds is used as a starting material. The method involves steps which ensure the full reaction of germanium tetrachloride in order to ensure that none is available to form germanium dioxide and steps which ensure the removal of any germanium dioxide.
