    摘要: Aliphatic alpha,omega-aminonitriles are prepared by partial hydrogenation of aliphatic alpha,omega-dinitriles at elevated temperatures and superatmospheric pressure in the presence of a solvent and of a catalyst by a process in which the catalyst (a) contains a compound based on a metal selected from the group consisting of nickel, cobalt, iron, ruthenium and rhodium and (b) contains from 0.01 to 25% by weight, based on (a), of a promoter based on a metal selected from the group consisting of palladium, platinum, iridium, osmium, copper, silver, gold, chromium, molybdenum, tungsten, manganese, rhenium, zinc, cadmium, lead, aluminum, tin, phosphorus, arsenic, antimony, bismuth and rare earth metals and (c) from 0 to 5% by weight, based on (a), of a compound based on an alkali metal or on an alkaline earth metal, with the proviso that the component (a) is not based on iron or iron and one of the metals selected from the group consisting of cobalt, ruthenium and rhodium when (b) is a promoter based on a metal selected from the group consisting of titanium, manganese, chromium and molybdenum, and with the further proviso that, when a compound based on only ruthenium or ruthenium and rhodium or nickel and rhodium is selected as component (a), the promoter (b) may be dispensed with.

    摘要: A process for the catalytical preparation of condensation products of formaldehyde, in which formaldehyde or a formaldehyde-forming compound is caused to undergo reaction using a catalyst which has been produced, in the presence of an auxiliary base, from a triazolium salt of formula I ##STR1## in which R.sup.1 and R.sup.3 are the same or different and stand for aliphatic groups having from 1 to 30 carbon atoms, optionally substituted aryl groups, optionally substituted aralkyl groups, and/or optionally substituted heteroaryl groups,R.sup.2 represents hydrogen, the hydroxymethylene group --CH.sub.2 OH or the hydroxy-hydroxymethylene-methylidyne group --CH(OH)(CH.sub.2 OH), andR.sup.4 denotes hydrogen, a halogen atom, a nitro or cyano group, an aliphatic group having from 1 to 30 carbon atoms, an optionally substituted aryl group, an optionally substituted aralkyl group, an optionally substituted heteroaryl group, an alkoxy group --OR.sup.5, a thioether group --SR.sup.6, an amino group --NR.sup.7 R.sup.8, an acyl group--COR.sup.9 or an ester group --COOR.sup.10, where R.sup.5, R.sup.6, R.sup.7, R.sup.8, and R.sup.9 stand for radicals such as those stated above for R.sup.1, and R.sup.10 is a C.sub.1 -C.sub.10 alkyl group or an optionally substituted aryl or aralkyl group, orR.sup.3 and R.sup.4 together form a C.sub.3 -C.sub.5 alkylene or C.sub.3 -C.sub.5 alkenylene group or a C.sub.6 -C.sub.14 alkylene group, or a C.sub.7 -C.sub.14 aralkylene or C.sub.8 -C.sub.14 aralkenylene bridging member, andA is the equivalent of an anion having one or more negative charges for electrical neutralization of the charge on the triazolium cation.
