Abstract: PROBLEM TO BE SOLVED: To provide a molded catalytic structure having a shape to uniformize the flow velocity of a gas passing through the inside of a catalyst and accordingly having a shape to prolong the service life of the catalyst because of its uniform thermal stress. SOLUTION: The molded catalytic structure has an upstream end face 3, a downstream end face 4 and a circumferential face 5. In this case, the upstream end face is formed in the shape of the side face 8 of a conical or truncated- conical protrusion 7, and the side face 8 has at least a concave curved surface.

Abstract: The invention relates to a method for producing polyisocyanates by reacting primary amines with phosgene, comprising the following steps: a) mixing the amine with the phosgene; b) reacting the amine with the phosgene in a reactor, inside of which the mixture stays for a period of time and, optionally; c) transferring the discharge from the reactor from step b) into a distillation column. The invention is characterized in that the reactor cited in step b) is provided in the form of a tubular reactor.

Abstract: Starting material streams are mixed in a mixer (13) for the phosgenation of amines by a process in which the reaction product (3) is removed in a closed loop and the starting material streams (1.2) contain organic solvents. The main streams (1.1, 2.1) and/or part-streams (1.2, 2.2) of the starting materials (1, 2) come into contact with one another according to the countercurrent principle.

Abstract: Method for purifying isocyanates (I) by distillation. Method for purifying isocyanates by distillation comprises: (a) first separating a stream (1) containing (I), high and low boilers and non-evaporatable residue (X) by distillation (at least one theoretical plate) into a sidestream (2), containing (I) and (X), and a vapor stream (3), containing (I) and low boilers; (b) (X) in (2) is kept separate from (3) and/or material streams that consist at least partly of (3); (c) another (I)-containing vapor stream (4) is separated from (2), leaving stream (8) consisting essentially of (X); (d) streams (4) and (3) are separated by distillation into 3 streams (5,6,7) of different boiling ranges, where the lowest boiler (5) contains a significant proportion of the low boilers in (1), the highest boiler (7) contains a significant proportion of the high boilers in (1) and the middle stream (6) is essentially (I).
