    Abstract: PCT No. PCT/EP97/01113 Sec. 371 Date Sep. 4, 1998 Sec. 102(e) Date Sep. 4, 1998 PCT Filed Mar. 5, 1997 PCT Pub. No. WO97/32866 PCT Pub. Date Sep. 12, 1997A noble metal-free catalyst composition is obtainable by a) preparing an aqueous mixture comprising i) a salt of at least one base metal selected from among the elements having atomic numbers 21-32, 39-42, 48-51, 57-75 and 81-83; ii) phosphate ions; and iii) at least one nitrogen source; and b) evaporating the aqueous mixture obtained and drying the catalyst composition thus formed. The catalyst composition prepared can be used for producing hydrogen peroxide and for the epoxidation of olefins.

    Abstract: The process comprises reacting 2-, 3- or 4-pentenenitrile or mixtures thereof with carbon monoxide and a hydroxyl compound in the presence of a catalyst system comprising (i) a palladium(II) compound, (ii) a bidentate diphosphine ligand and (iii) an anion source. Novel catalyst systems containing diphosphine ligands of the bis(phosphinomethyl)amine type are also described.

    Abstract: A description is given of a process for preparing methyl formate by reacting excess methanol with carbon monoxide under superatmospheric pressure and at elevated temperature in the presence of alkali metal methoxide or alkaline earth metal methoxide as catalyst in a pressure-rated reactor, in which the use of at least two reactor elements, preferably operated in countercurrent, at about 100° C. and a pressure of about 100 bar in combination with a solids-free desalting of the reaction product makes possible very economical, largely trouble-free production of methyl formate in any desired quality and with a very good production capacity. Furthermore, the process for solids-free desalting and apparatuses for carrying out this process are described.

Date Dec. 18, 1997An oxidation catalyst based on titanium silicalites or vanadium silicalites having a zeolite structure and containing from 0.01 to 30% by weight of one or more noble metals selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium, platinum, rhenium, gold and silver has been molded by a compacting shaping process. This oxidation catalyst is used for the preparation of epoxides, in particular propylene oxide, from olefins, hydrogen and oxygen.
