KEEPING UP WITH CHEMISTRY The amphoteric character of metallic hydroxides. R. S ~ O L - ing of methanol for anti-freeze has been handicapped materially DER. Z. engew. Chm.. 43, 509-12 (Aug. 5, 1933).-From con- by lack of knowledge and also somewhat by the unsavory reputacentrated true solutions of hydroxides of divalent metals it is tion of this chemical, most of which seems wholly unwarranted by possible t o isolate hydroxo salts. The metallic hydroxides act the facts. Its toxicity has been greatly exaggerated. Proposed as so-called anhydro acids which by the absorption of water or specifications of methanol for anti-freeze are: (1) T~alles: not sodium hydroxides are transformed into hydroxo acids or salts. less than 97%.
