Abstract: The prepn. of 1,2-dichloroethane comprises by oxychlorination of ethylene in the presence of a Cu chloride catalyst on a support of alumina, with concns. in Cu of 1-20 wt.%. The support consists of eta-, theta-, eta-, delta-, or chi -alumina or a mixt. of these oxides. The reaction occurs in (series of) reactors fo which >=1 is subdivided into succesive reaction zones, with increasing catalystic activity. The first reaction zone at least of the subdivided reactor(s) contains the supported catalyst as described. The catalytic system gives an increase in the yield of 1,2-dichloroethane, compared with catalytic systems using Cu chloride on a gamma-alumina support. The formation of chlorinated sec. prods. and of ethylene oxides is reduced, that of ethylene chloride e.g. by 30-50 wt.%.

Abstract: A supported catalyst containing copper and alkali metals, wherein the content of copper is from 1.0 to 12% by weight, based on total catalyst and expressed as metal, and the total content of the alkali metals potassium, lithium and sodium is from 0.3 to 9% by weight, based on total catalyst. The novel catalyst is useful for the preparation of 1,2-dichloroethane by oxychlorination of ethylene.

Abstract: Catalyst for hydrogenation of organic cpds. contains one or more complexes of Pd(O) on an inert carrier. This catalyst is very active, esp. with respect to hydrogenation of organic nitro or carbonyl cpds., nitriles, olefins and cycloolefins. The reaction is highly selective, esp. in the case of aromatic and polycyclic nitro cpds. The Pd(O) complexes are stable and firmly adhere to the carrier. The organic ligands protect Pd atoms against oxidation. The dispersion of Pd atoms is very fine. The pref. ligands include unsatd. ketones of formula (in which R1 and R6 are each H, 1-5C alkyl, phenyl or 5-8C cycloalkyl; and R2, R3, R4 and R5 are each H (pref.) or 1-5C alkyls).

Abstract: Prodn. of a Pd-C catalyst involves redn. of Pd cpds. by adding a soln. of a Pd salt to an organic solvent (MeOH) contg. O gps. in the presence of suspended C, with stirring in a H2 atmos. Pref. redn. is carried out in normal or elevated pressure, pref. 1-10 bar. The C carrier can be powdered active charcoal, C black or graphite. Catalyst is used in the hydrogenation and hydrogenative cracking of organic cpds. Method gives a partic. active catalyst.

Abstract: Carbonyl compounds R1-CHR2-CHR3-CR4O (I, R1=H or an organic radical; R2-R4=H or C1-C4-alkyl) are prepared by selective hydrogenation of the alpha , beta -unsaturated carbonyl compounds R1-CR2=CR3-CR4O (II) in the liquid phase by means of hydrogen in the presence of a palladium catalyst and of from 15 to 50% by weight, based on (II), of a tertiary amine.
