摘要:The present invention relates to a method for preparing an electroactive metal polyanion or a mixed metal polyanion comprising forming a slurry comprising a polymeric material, a solvent, a polyanion source or alkali metal polyanion source and at least one metal ion source; heating said slurry at a temperature and for a time sufficient to remove the solvent and form an essentially dried mixture; and heating said mixture at a temperature and for a time sufficient to produce an electroactive metal polyanion or electroactive mixed metal polyanion. In an alternative embodiment the present invention relates to a method for preparing a metal polyanion or a mixed metal polyanion which comprises mixing a polymeric material with a polyanion source or alternatively an alkali metal polyanion source and a source of at least one metal ion to produce a fine mixture and heating the mixture to a temperature higher than the melting point of the polymeric material, milling the resulting material and then heating the milled material. It is another object of the invention to provide electrochemically active materials produced by said methods. The electrochemically active materials so produced are useful in making electrodes and batteries.

标题:Synthesis of chrome-complexed dye developers in the presence of weakly basic anion exchange resins
发明人：BADER HENRY; FEINGOLD MICHAEL H
权利人:POLAROID CORP
摘要:An improved method for preparing a compound of the formula: ##SPC1## n Where each R can be hydrogen, an alkyl substituent, preferably having from 1-6 carbon atoms or an alkoxy substituent preferably having from 1-6 carbon atoms and each R 1 is hydrogen or an alkyl or an alkanol group. R 2 is an alkylene radical having from 1-6 carbon atoms and X represents the atoms to complete a cyclopentyl or cyclohexyl ring. n Metal complexed dyes of the above formula are especially useful in the preparation of photographic image patterns. n The improved feature of the method presented involves the preparation of compounds of formula 1 in the presence of weakly basic anion exchange resins to obtain high yields of especially high purity products.

标 题 :Synthesis of alkylaromatic compounds
发明人：IMAI TAMOTSU
权利人:UOP INC
摘要:Alkylaromatic compounds may be synthesized by reacting an aromatic compound with a mixture of carbon monoxide and hydrogen at alkylation conditions in the presence of a dual-function catalyst. The catalyst system will comprise (1) a composite of oxides of copper, zinc and aluminum or chromium, and (2) an alumino-silicate which may be either in crystalline or amorphous form.
