The invention relates to a continuous method for producing an isocyanurate-containing isocyanate mixture, in which in a step a) a mixture of a first and a second isocyanate component and an isocyanate group trimerization catalyst is provided; in a step b) the mixture obtained in step a) is reacted in a first residence time zone at an elevated temperature; in a step c), the reaction mixture obtained in step b) is further heated in a second residence time zone, optionally after adding a stopper; and in a step d), the reaction mixture obtained in step c) is cooled down in a third residence time zone by way of lowering the temperature, thus obtaining the desired isocyanurate-containing isocyanate mixture.

A method of reacting phosgene with a second compound containing one or more of hydroxyl, thil, amino and/or formamide groups, wherein phosgene has a GHS hazard identification of GHS06 and is obtainable from the reaction of carbon monoxide and chlorine and wherein the second compound is capable of a chemical reaction with phosgene is provided.

Method for the phosgenation of compounds comprising hydroxyl, thiol, amino and/or formamide groups

Aromatic amines are produced by adiabatic hydrogenation of nitroaromatic compounds in the gas phase on one or more fixed catalysts. The nitroaromatic reactant is passed over the catalyst under pressure and at elevated temperature with hydrogen, water, optionally nitrogen and substantially in the absence of the aromatic amine produced from the nitroaromatic.
