Abstract: Reacting an organic compound (I) in the presence of a catalyst, in which the catalyst comprises a homogeneous ruthenium compound or a mixture of two or more such compounds, deposited in situ on a support. Also claimed is a supported catalyst which is obtained by deposition of Ru compound(s) as above, by passing a solution of Ru compound(s) through or over a support.

Abstract: Hydrogenation of an aromatic ring containing at least one OH or amino group in the presence of a catalyst comprising at least one group I, VII or VIII metal and a carrier is characterised in that the catalyst is prepared by: (a) dissolving the active component of the catalyst or its precursor in a solvent; (b) treating the solution with an organic polymer that in situ binds at least 10 times its weight in water to give a swollen polymer; (c) mixing the polymer with the catalyst support material; and (d) shaping the mass, drying and calcining.

Abstract: Method (M) of hydrogenation of sugar(s) (I) to sugar alcohol(s) (II), comprises contacting at least one (I) with hydrogen in presence of a catalyst. Method of hydrogenation of sugar(s) (I) to sugar alcohol(s) (II), comprises contacting at least one (I) with hydrogen in presence of a catalyst. Catalyst is a monolithic supported catalyst obtained by: (a) successively heating and cooling a metal fabric or film carrier in air; (b) coating with active component (i.e. at least one Group VIII metal, optionally together with at least one Group I or VII transition metal) under vacuum; (c) cutting and shaping; and (d) processing to give the monolithic catalyst. An independent claim is also included for the synthesis of vitamin C, including the preparation of sorbitol from glucose by (M).

Abstract: Preparation of N-alkyl-substituted amino-alkynes of formula R1-C IDENTICAL C-CR2R3-NR4R5 comprises the heterogeneous reaction of an alkyne of formula R1-C IDENTICAL CH, a carbonyl compound of formula R2R3C=O and an amine of formula R4-NH-R5 using an unsupported copper catalyst derived from malachite. R1 = H, alkyl, haloalkyl, cycloalkyl, aryl, alkoxy, alkoxyalkyl or hydroxyalkyl; R2, R3 = H, alkyl, haloalkyl, aryl or alkoxy; R4, R5 = H, alkyl, haloalkyl, aryl, alkoxy or hydroxyalkyl; or NR4R5 = a 5-6 membered heterocycle.
