摘要:The present invention relates to a novel method of synthesis of unsolvated mixed cation borohydrides of a general formula M x M′ y (BH 4 ) z , where M and M′ stand for metal cations, x, y, and z are stoichiometric coefficients. The method of synthesis according to the present invention is characterised in that the precursors having a general formula M[A n ] u and [Cat] v M′(BH 4 ) w are used for the synthesis, where [An] stands for a weakly coordinating anion; [Cat] stands for weakly coordinating cation; u, v, and w are the stoichiometric coefficients; and the synthesis is carried out under an inert to the reagents atmosphere—according to the general reaction equation: x M[An] u +y [Cat] v M′(BH 4 ) w →M x M′ y (BH 4 ) z +xu [Cat][An] where z=yw, xu=yv; M x M′ y (BH 4 ) z is the product of the reaction.

标 题 :Synthesis of hydrogen perfluoroalkanes
发明人：DURUAL PIERRE; LANTZ ANDRE
权利人:ATOCHEM ELF SA
摘要:The invention relates to the synthesis of hydrogenperfluoroalkanes R F H, R F denoting a perfluoroalkyl radical containing 2 to 20 carbon atoms, by reaction of the corresponding perfluoroalkyl iodide R F I with an alkali metal hydroxide. n The use of methanol as solvent allows the formation of tars to be avoided, an almost total conversion of R F I and an R F H of excellent purity to be obtained, and the alkali metal iodide by-product to be recovered easily.

标题 :Ion-exchange structures of copolymer blends
发明人：MOLNAR CHARLES J; PRICE EDWARD H; RESNICK PAUL R
权利人:DU PONT
摘要:Ion-exchange films, membranes and laminar structures incorporating a layer of a blend of a first fluorinated polymer which contains sulfonyl groups in ionizable form and a second fluorinated polymer which contains carboxylic acid functional groups, when used to separate the anode and cathode compartments of an electrolysis cell, permit operation at high current efficiency and low power consumption. They can be made by synthesis of precursor polymers in melt-fabricable form, blending, fabrication of the film, membrane or laminar structure, and hydrolysis of the functional groups to ionizable form, such as the free acid form or alkali metal salt thereof.
