Abstract: front page image
(EN)Stabilisation against water uptake of hygroscopic salts useful as catalysts by formation of anhydrous adducts with particulate support materials in order to facilitate manipulation and storage. The adducts comprise a particulate support material and a hygroscopic salt of a species of formula R1R2R3R4N, R1R2R3R4P, R1R2R3R4As, wherein R1-R4 which may be identical or different represent hydrogen or alkyl or aryl groups, or of Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba, Cu, Ag, Zn, Cd, Au, Hg, Ga, In, Tl, Sn, Sb or Pb, the salt anion being fluoride, bromide, chloride, sulphate, nitrate, nitrite, cyanate, thiocyanate, peroxide, hydroxide, acetate, formate or comprises phosphorus and oxygen, the salt being coated on the support material thereby being rendered less hygroscopic; provided that when the species is Na, the anion is other than hydroxide and when the species is Tl the anion is fluoride, bromide or chloride. Adducts of salts useful in catalytic fluorination, e.g. R1R2R3R4N+F- and CsF are of especial interest.
(FR)L"absorption d"eau par des sels hygroscopiques utilises comme catalyseurs, peut etre stabilisee par la formation de produits d"addition anhydres avec des matieres sous forme de particules servant de support, facilitant ainsi la manipulation et le stockage. Les produits d"addition comprennent une matiere sous forme de particules servant de support et un sel hygroscopique de formules R1 R2 R3 R4N, R1 R2 R3 R4P, R1 R2 R3 R4 As, dans lesquelles R1 a R4, identiques ou differents, representent l"hydrogene ou des groupes alkyles ou aryles ou un sel de Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Bo, Cu, Ag, Zn, Col, Au, Hg, Ga, In, Tl, Sn, Sb ou Pb, l"anion du sel etant un fluorure, un bromure, un chlorure, sulfate, nitrate, nitrite, cyanate, thiocyanate, peroxyde, hydroxyde, acetate, formate ou comprend un phosphore et de l"oxygene, le sel formant un revetement sur la matiere formant support ce qui le rend moins hygroscopique; il est entendu que lorsque le sel est un sel de sodium, l"anion n"est pas un hydroxyde et lorsque le sel est un sel de Tl, l"anion est un fluorure, un bromure ou un chlorure. Les produits d"addition de sels, utilises dans la fluoration catalytique, par exemple R1 R2 R3 R4 N+F- et CsF ont un interet tout particulier.
