Action of Organic Acid on Beryllium Carbonate or Basic Carbonate. This method is similar in all respects to the above procedure. While it has been used most extensively for only the simpler members of the series, there is no apparent reason why it should not be equally effective for the preparation of other members as well. The procedure is one of the few claimed to give the basic formate. Directions given for the preparation of the basic acetate (synthesis 3) and basic propionate (synthesis 3) represent modifications of this general procedure. 

The basic acetate and propionate of beryllium are prepared most conveniently from a reactive form of the basic carbonate. The composition and the reactivity of the starting material are variable, and it may therefore be necessary to prepare the so-called basic carbonate from some convenient source of beryllium, especially if the available carbonate dissolves with difficulty in either hot acetic or propionic acid. For properties of these compounds see page 7. 

Twenty-five grams of basic beryllium carbonate is treated with 125 ml. of propionic acid in a 400-ml. beaker. When evolution of carbon dioxide has ceased, the solution is transferred to a porcelain evaporating dish and evaporated on a... 

Various combinations of basic beryllium acetate, propionate, and benzoate were reacted with the acid chlorides of adipic, sebacic, /8-ethyladipic, tere-phthalic, and isophthalic acids. Solution viscosities of the products (in toluene) were very low. Elemental analytical data tended to confirm this fact by showing the presence of inordinate amounts of end groups.
