摘要:
The present invention describes an improved catalyst and process for the selective hydrogenation of nitro aromatics, nitrosoaromatics and aromatic hydroxyl amines to their corresponding amines using gaseous hydrogen, in the presence of soluble iron compounds as a catalyst and optionally other reducible groups.
摘要:
A process is disclosed for producing aromatic amines by catalytic hydrogenation of corresponding aromatic nitro compounds in the gaseous phase on fixed catalysts which contain one or several metals of groups VIIIa, Ib, IIb, IVa, Va, VIa, IVb and Vb of the periodic table of elements (Mendeleev) on a ceramic substrate with a BET surface of less than 40 m /g, at molar ratios from hydrogen to nitro group(s) from 3:1 to 30:1 and at temperatures in the catalytic bed from 180 to 500 DEG C. The process is characterised in that the aromatic nitro compound load of the catalyst is continuously or gradually increased from 0.01-0.5 to 0.7-5.0 kg/l x h, the maximum load being attained within 10 to 1000 hours. This process can be carried out without problems on an industrial scale and ensures a high space-time yield, together with an improved productivity of the catalysts used. 00000

摘要:
The present invention relates to tertiary amines of formula (I) for use in therapy, particularly for use in treating cardiovascular disorders. The compounds have been found to regulate phospholamban phosphorylation by interfering with the A-kinase anchor protein 18delta (AKAP185) binding to the PKA substrate phospholamban. The compounds share a tri(alkylaryl/alkylheteroaryl) amine structure.

摘要:
A curable epoxy resin adhesive, the adhesive comprising an epoxy resin component and a curing agent component. The curing agent component comprises first and second amine curing agents. Each of the first and second amine curing agents has a respective curing property determined by mixing the respective amine curing agent alone with a test epoxy resin to form a first or second curable mixture, and each curing property comprises a gel time when the curable mixture is at an ambient temperature of 25 °C and a peak exotherm temperature when the curable mixture is cured in air at a curing temperature of 70 °C. A ratio between the first and second gel times is from 4-15:1 and the second amine curing agent has peak exotherm temperature is higher than the peak exotherm temperature of the first amine curing agent by a temperature Δt which is at least 2°C.
