Abstract: Production of amines (I) by hydrogenating at least one nitro compound (II) in presence of a supported catalyst (A) that contains nickel as catalytically active metal, optionally together with at least one metal of subgroups I, V, VI and/or VIII. The reduced and stabilized catalyst contains nickel crystallites with a bimodal distribution of size, with maxima at 30-80 and 81-150 Angstrom , and after reduction at 100 degrees C has a degree of reduction at least 70%. The support is one or more of zirconia, hafnia and/or silica and the reduced and passivated catalyst contains, by weight, 60-80% nickel; 0-20% silica; 0-40% zirconia and 0-4% hafnia.

Abstract: The invention relates to a process for the preparation of amines by hydrogenation of nitro compounds, which comprises carrying out the hydrogenation in a vertical reactor whose length is greater than its diameter, having a downward-facing jet nozzle arranged in the upper region of the reactor through which the starting materials and the reaction mixture are fed in, and having an outlet at any desired point of the reactor, through which the reaction mixture is fed back to the jet nozzle in an external circuit by means of a conveying means, and having flow reversal in the lower region of the reactor.

Abstract: An active isocyanate (I) is prepared by mixing (A) an isocyanate with (B) an unsupported phosphite having two groups with a total of 2-60 carbon atoms. Independent claims are also included for: (i) a process for the preparation of a polyurethane (II) by reaction of a compound that is reactive with an isocyanate and a component containing the active isocyanate (I); (ii) the resulting polyurethane (II); (iii) a process to hinder the change in properties of a liquid isocyanate (A), preferably solidification, coloring, cloudiness, NCO content and/or absorption extinction coefficient at 2150-1615 cm by the addition of the phosphite (B) (iv) articles containing the active isocyanate (I) and/or the polyurethane (II).
