    摘要: A fluid-circulation heat exchanger including a porous body, made of thermally conductive material, in contact with at least one portion of a part to be cooled. The fluid flows through this porous body. The porous body has pores which generate directional changes of the fluid. These pores are large enough for the head loss of the fluid to be as small as possible on passage through the porous body. Application, in particular, to electron tubes.

    摘要: A method for preparing carboxylic acids by carbonylating a reagent, particularly an alcohol, in the presence of an iridium catalyst. According to the method, the liquid phase reaction is carried out in a first zone in the presence of an iridium catalyst, and the resulting reaction mixture is partially vaporised in a second zone. The vaporised fraction containing the carboxylic acid is later purified and the unvaporised liquid fraction containing the catalyst is recirculated to the first zone. The method is characterised in that said unvaporised fraction is contacted with carbon monoxide in such a way that this compound is not returned to the second zone.
