PREPARATION OF BIS-CARBOXY ETHYL GERMANIUM SESQUIOXIDE AND ITS PROPIONIC ACID DERIVATIVES |
摘要 |
Reaction mixture of germanium dioxide and hypophosphorous acid or its salts in hydrochloric acid is extracted with organic solvent. This resultant is then reacted with acrylic acid or its derivatives, and further hydrolyzed to provide bis-carboxy ethyl germanium sesquioxide or its propionic acid derivatives. |
