Abstract: The present invention relates to a process for hydrogenating organic nitriles by means of hydrogen in the presence of a catalyst in a reactor, where the shaped body catalyst is arranged in a fixed bed, wherein the shaped body in the shape of spheres or rods has in each case a diameter of 3 mm or less, in the shape of tablets a height of 4 mm or less, and in the case of all other geometries in each case has an equivalent diameter L = 1/a' of 0.70 mm or less, where a' is the external surface area per unit volume (mms 2/mmp 3), with: (I) where Ap is the external surface area of the catalyst particle (mms 2) and Vp is the volume of the catalyst particle (mmp 3). The present invention further relates to a process for preparing downstream products of isophoronediamine (IPDA) or N,N-dimethylaminopropylamine (DMAPA) from amines prepared according to the invention.

Abstract: The invention relates to a process for a continuous production of polyetherols comprising the steps of reacting of an alcohol (3) with a starter (5) or an alkoxylated precursor to give a mixture comprising an alcoholate and water, removing the water from the mixture by distillation,if appropriate feeding the alcoholate into a bubble column (23), having an inclination of from 0 to 90 to the horizontal, the bubble column (23)being divided into at least two compartments (25), wherein the compartments (25) are divided from each other by a dividing wall (27), the dividing wall (27) having a height, that liquid can flow over the dividing wall (27) from one compartment (25) into an adjacent compartment, feeding of alkylene oxide into at least one compartment (25) at the bottom of the compartment such that the alkylene oxide rises in the alcoholate, reacting of the alkylene oxide with the alcoholate or a secondary product being formed by the reaction of the alcoholate with alkylene oxide to give the polyetherol, discharging the reaction product from the bubble column (23).
