    Abstract: A process for the production of fluorochlorocarbon-free, urethane-containing, softelastic, semirigid or rigid moldings having a cellular core and a compacted peripheral zone and an essentially pore-free, smooth surface involves reacting a) an organic and/or modified organic polyisocyanate with b) at least one relatively high-molecular-weight compound containing at least two reactive hydrogen atoms, and, if desired, c) a low-molecular-weight chain extender and/or cross linking agent, in the presence of d) a blowing agent, e) a catalyst, f) at least one amorphous, microporous silica gel which preferably has a mean pore diameter with a frequency of occurrence of more than 40 % in the range from 0.1 to 10 nm, a pore volume of from 0.15 to 1.8 ml/g and a BET surface area of from 200 to 900 m2/g, and, if desired, further additives and g) assistants, in a closed mold with compaction.

    Abstract: Process for hydrogenating an organic compound having at least one carbonyl group, in which the organic compound is contacted, in the presence of hydrogen, with a shaped body which is producible in a process in which (i) an oxidic material comprising copper oxide and aluminum oxide and at least one of the oxides of iron, lanthanum, tungsten, molybdenum, titanium, zirconium, tin or manganese, and if appropriate additionally tin oxide and/or manganese oxide, is provided, (ii) pulverulent metallic copper, copper flakes, pulverulent cement, graphite or a mix-ture thereof are added to the oxidic material, (iii) the mixture resulting from (ii) is shaped to a shaped body and (iv) the shaped body is treated with water or steam.
