摘要： A shell-and-tube apparatus, more specifically, a shell-and-tube reactor, which includes a vessel, at least one intermediate tube plate sectioning the interior of the vessel into at least two compartments having different temperatures, a number of heat transferring tubes penetrating the intermediate tube plate or plates, and a fluid passing through the tubes which is heated or cooled by a heat transfer medium surrounding the tubes. At least one insulation plate or plates are provided on one or both sides of the intermediate tube plate so that the space between the intermediate tube plate or plates and, if two or more insulation plates are used, the space or spaces between the insulation plates may be utilized as a stagnation zone for the heat transfer medium, so as to make the temperature gradient through the intermediate tube plate or plates gentle and relax the thermal stress occurring in the body wall. The reactor is particularly useful for production of (meth)acrolain and/or (meth)acrylic acid by catalytic gas-phase oxidation of propylene or butenes.

摘要： In the plating for electrodeposition of aluminum using a mixed molten salt bath comprising an aluminum halide and a quaternary ammonium salt, the mixed molten salt bath comprises from 20 to 80 mol % of the aluminum halide and from 20 to 80 mol % of a 1-alkyl- or 1,3-dialkylimidazolium halide, provided that the alkyl group has 1 to 12 carbon atoms, by the use of which the plating can be carried out at a high current density of not less than 30 A/dm.sup.2 without generation of burnt deposits, which has been difficult to carry out using the conventional molten salt bath. Addition of a halide of an alkali metal or alkaline earth metal, or an organic solvent, to the above plating bath can improve conductivity and also enhance uniform electrodeposition performance.

摘要： A process for producing a perovskite-type oxide of the ABO.sub.3 type is disclosed. A solution of an element A (Pb, Ca, Sr and/or La) and an element B (Ti and/or Zr) is brought into contact with oxalic acid in the presence of an alcohol to precipitate oxalic acid salts; the acid radicals in the solution are neutralized with an amine or ammonia; the resulting precipitate is then subjected to calcination.A fine-grained ferroelectric oxide having a sharp grain size distribution can be produced, with its chemcial composition being exactly controlled. This oxide is suitable for use as a piezoelectric, pyroelectric or ferroelectric material.
