    Abstract: Disclosed is a method for producing organic disulphide by oxidation of the corresponding thiol with sulphur disolved in organic disulphide using an amine as a catalyst in a reaction column (K). The thiol used is a crude thiol flow from catalytic reaction of the corresponding primary alcohol with hydrogen sulphide and the bases of the reaction column (K) are temperable.

    Abstract: The invention relates to a reactor (R) for performing a three-phase react ion of a fluid phase (1) and a gaseous phase (2) on a packed bed catalyst (F ), the packed bed catalyst (F) being disposed horizontally in the reactor (R ) and the fluid phase (1) and the gaseous phase (2) being fed through the re actor (R) from the bottom to the top, using a mixing and distributing device (MV) across the packed bed catalyst (F), characterized in that the mixing a nd distributing device (MV) comprises a trough distributor (TV) for the flui d phase (1) having trough-shaped channels (K) and drain tubes (A) in the tro ugh-shaped channels (K) for the fluid phase (1), and a distributor floor (B) disposed below and at a distance from the trough distributor (TV) in which vertical spouts (T) are disposed, having one or more openings (P1) for the i nlet of the gaseous phase (2) and one or more openings (P2) disposed below t he openings (P1) for the inlet of the gaseous phase, for the inlet of the fl uid phase (1) into the spouts (T), and the number and size of the openings ( P2) for the inlet of the fluid phase (1) being designed such that the fluid level on the distribution floor (B) is adjusted to be below the openings (P1 ) for the inlet of the gaseous phase (2) and above the openings (P2) for the inlet of the fluid phase (1) for a prescribedinlet flow of fluid.
