| 摘要 |
This invention comprises novel chromium tris-diorgano-orthophosphates, including coordination polymers thereof, and their preparation by the reaction of certain simple salts or esters of trivalent chromium with alkali or alkaline earth metal salts of diorgano orthophosphoric acid and separation of the novel compounds. The simple salts or esters include primarily the halides, nitrates, sulfates and acetates of trivalent chromium. The alkali metal salts or alkaline earth metal salts of diorgano orthophosphoric acids include primarily compounds of the general formula M' [OP(O)(OR)2]n in which M' is an alkali metal or an alkaline earth metal, each n is the valence of such metal and each R can be an alkyl, alkoxyalkyl or cycloalkyl group of one to about eight carbon atoms and the chlorinated and brominated derivatives thereof. |
