    Abstract: In the production of alcohols by gas phase hydrogenation of carboxylic acids or esters at elevated temperature and pressure in the presence of catalysts containing or consisting of group IV oxide(s) as hydrogenation-active constituent, hydrogenation is carried out (a) at 250-400 degrees C and 5-100 bar in the presence of (b) primary or secondary alcohols, using a hydrogen to alcohol molecular ratio ≤ 800.

    Abstract: Colloidal palladium for hydrogenating olefins, acetylene, dienes and (un)saturated nitriles consists of palladium clusters having an average particle size of 0.2-2.0 nm. At least 80% of the palladium clusters have a particle diameter which deviates not more than 0.2 nm from the average particle diameter. The clusters have protective ligands on the surface. Independent claims are also included for: (1) production of a palladium colloidal solution by reacting a palladium salt with a reductant made of 4-30 C alcohol, and a protective ligand of phosphane and/or aromatic nitrogen compound at 0-300o C; (2) production of colloidal palladium comprising forming the above palladium colloidal solution, precipitating the colloidal palladium by adding a hydrocarbon solvent, removing the colloidal palladium, and drying; and (3) production of a palladium-containing heterogeneous catalyst by forming the palladium solution as above, impregnating a carrier selected from alumina, silicon dioxide, zirconium dioxide, titanium dioxide, carbon, zeolite and silicate.

    Abstract: Prodn. of radiation-hardenable acrylate compsns. comprises: (i) the addn. of a cpd. (A) contg. acrylic gps. to a non-radically copolymerisable benzophenone deriv. contg. prim. or sec. amine gp(s), or OH gp. or mercapto gp.. Also claimed are: (1) radiation hardened materials contg. radiation hardenable acrylate compsns.; (2) benzophenone derivs. of formula RCOR (I) as novel cpds.; and (3) prepn. of the novel cpds. (I). R = phenyl or R ; R = a gp. of formula (II); and R -R = H, 1-4C alkyl or 1-4C alkoxy, with 1-3 of gps. R -R being a 1-30C organic gp. (X) with a prim. or sec. amine gp., OH gp. or mercapto gp..

    Abstract: The novel features in bulk or soln. polymerisation (esp. styrene/acrylonitrile copolymer mfr.) involving feed of the reaction components to a recycle reactor are that: (a) the reactor has at least one tubular bundle reactor (1) with straight or upright tubes sprinkled with a fluid heat-exchange medium; and (b) each tubular bundle reactor (1) consists of at least two tubular bundle heat exchangers (1A, 1B) linked to each other via at least one intermediate mixing zone, pref. a static mixer (12). The appts. is also claimed per se.
