    摘要: Desublimator for isolating sublimation products from reaction gases, which consists of a closed housing and a plurality of rows of finned tubes accommodated horizontally and superposedly therein, successive superposed finned tubes being supported, and mutually spaced, with limited adjustability, by means of cage-like perforated sliding shoes surrounding them in a box-like manner, the sliding shoes of the individual finned tubes being directly stacked one above the other and resting loosely on common supporting girders anchored to the housing, and the supporting girders having, in cross-section, the outline of a triangle with its apex pointing downward.

    摘要: A supported catalyst, containing vanadium pentoxide, titanium dioxide, phosphorus, rubidium and any optionally added cesium, with or without zirconium dioxide, in which the catalytic material contains from 1 to 40% by weight of V.sub.2 O.sub.5, from 60 to 99% by weight of TiO.sub.2 and/or ZrO.sub.2 and, based on the total amount of TiO.sub.2, ZrO.sub.2 and V.sub.2 O.sub.5, up to 2% by weight of phosphorus and up to 1.5% by weight of rubidium and/or cesium, and which comprises two layers, of which the inner layer contains more than 0.2 and up to 2% by weight of phosphorus, but no rubidium and/or cesium, and the outer layer contains from 0 to 0.2% by weight of phosphorus and from 0.02 to 1.5% by weight of rubidium and/or cesium, the outer layer accounting for from 10 to 90% by weight of the total catalytic material.
