Abstract: PROBLEM TO BE SOLVED: To improve the storability and handleability of fatty acids by catalytically hydrogenating only carbon-carbon double bonds in the fatty acids and fatty acid derivatives by using a colloid of noble metal as a catalyst without using solvent. SOLUTION: Fatty acids and/or fatty acid derivatives are catalytically hydrogenated selectively under a hydrogen pressure up to 800 bar at maximum by using a catalyst that is a colloid of a single metal, binary or multiple metals selected from the group VIII or IB in the periodic table and is stabilized with a surfactant, for example, an amphoteric betain, or a solution catalyst prepared by dissolving the above-stated catalyst (the homogeneous catalyst) or, a heterogeneous catalyst, that are prepared by using previously formed single, binary or multi-metal colloid and their solutions and depositing them on a carrier. In a preferred embodiment, a bulk type carrier-supported catalyst is used to effect the catalytic hydrogenation reactions in a fixed bed reactor or in a tubular reactor.

Abstract: Multi-metal catalyst containing iridium and at least one doping element on a support uses at least one element chosen from manganese, cobalt, iron, nickel, copper or ruthenium as the doping agent for iridium. The preparation of substituted aromatic amines by hydrogenating the corresponding substituted aromatic nitro compounds in the presence of the above catalyst is also claimed.

Abstract: Furnace carbon black which has an H content of greater than 4000 ppm and a peak integral ratio of non-conjugated H atoms (1250-2000 cm-1) to aromatic and graphitic H atoms (1000-1250 cm-1 and 750-1000 cm-1) of less than 1.22. It is produced by injecting the liquid carbon black raw material and the gaseous carbon black raw material at the same point in a furnace carbon black process. The furnace carbon black may be used in the preparation of electrocatalysts.

Abstract: The invention related to a platinum/ruthenium alloy catalyst that comprises finely-dispersed alloy particles on a powdery, electrically-conductive carrier material, methods of making it, and its use in fuel cells having a polymer electrolyte membrane. The catalyst is particularly resistant to carbon monoxide poisoning when the alloy particles display mean crystallite sizes of 0.5 to 2 nm.

Abstract: The prodn. of 2,2'-bis-(4-hydroxyphenyl)-propanes (BHPP) comprises reacting the corresp. phenols and carbonyl cpds. at 40-150 degrees C in presence of a formed acid catalyst consisting of a sulphonate gp.- and mercapto gp.-contg. organopolysiloxane (OFP) contg. units of formula (O3/2SiR'SO3)M(x+) (I) and O3/2SiR SH (III). In (I) and (III), R = 1-12C alkylene, 5-8C cycloalkylene or a gp. of formula -(CH2)n-Cyc-(CH2)m- or -(CH2)n-Phe-(CH2)m- (II) (with n, m = 0-6, i.e. the no. of Si- or S-linked CH2 gps.; Cyc = cyclohexylene; Phe = phenylene); M = H, opt. NH4, or a metal with a valency of x = 1-4; R = R . The free valencies of the O atoms attached to Si are taken up by the Si atoms of other gps. (I) and/or (II) and/or by the metal atom-oxygen gps. of crosslinking bridging gps. of formula SiO4/2 (IV) and opt. R''SiO3/2, R'SiO3/2, R'2SiO2/2, AlO3/2, R'AlO2/2, TiO4/2, R'TiO3/2 and R'2TiO2/2 (V). In (V) and (IV), R' = Me or Et; R" = Ph or 2-12C alkyl. The ratio of gps. (I):(III) = (10:1)-(1:10), the ratio of (I):(IV) = (1:3)-(1:20), and the ratio of (IV):(V) = (1:0)-(1:0.5). The required prod. is then isolated.
