The present invention relates to a process for the one-pot hydrogenation and dehydration or isomerization of an organic compound, and to a catalyst composition for this process comprising transition metal particles having particle size below 50 nm supported on a material comprising at least one fluorinated polymer (P), wherein polymer (P) bears -SO2X functional groups, X being selected from X' and OM, X' being selected from the groups consisting of F, CI, Br and I; and M being selected from the group consisting of H, and alkaline metal and NH4.
A flexible, breathable laminate is provided for use in, for example, hospital gowns ortents, which is capable of preventing liquids from passing inwardly while at the same time permitting water vapour, such as perspiration, to pass out outwardly. The article comprises an inner layer of hydrophobic material (2) having a moisture vapour transmission rate exceeding 1000 gms/m2 day and an advanced water contact angle exceeding 90 degrees, and an outer attached layer of hydrophilic material (4) having a moisture vapour transmission rate exceeding 1000 gms/m2 day.
The outer layer can contain a solid particulate or a liquid , additive, such as a pigment or antistatic compound, the layer (2) optionally being attached to a textile layer (6).
When N-fluoropyridinium salt of the following formula is prepared by reacting a pyridine compound with a Brønsted acid and fluorine, an excess amount of the pyridine compound relative to the amount of the Brønsted acid being used, a high yield results.

La présente invention concerne de nouvelles membranes échangeuses d'ions, leur méthode de préparation et leurs utilisations. Les membranes sont faites d'un polymère obtenu à partir d'un monomère ou d'un mélange de monomères bifonctionnel de formule générale [T-SO2-Y-SO2T']- M+. Les polymères sont en outre utiles dans les piles électrochimiques, dans un procédé d'électrolyse chlore-soude, comme séparateur dans une préparation électrochimique de composés organiques et inorganiques, comme séparateur entre une phase aqueuse et une phase organique, ou comme catalyseur pour les additions Diels-Alder, les réactions Friedel-Craft, les condensations aldol, la polymérisation cationique, les estérifications, et la formation d'acétals.
