Procedure for the reaction of a first compound with a second compound, in which the first compound has a labeling of dangerous substance according to GHS of GHS06 and can be obtained from the reaction of at least one first fluid precursor compound and a second fluid precursor compound and wherein the second compound is capable of a chemical reaction with the first compound, comprising the steps: (I) providing a liquid phase, containing the second compound, in a reactor with an upper and a lower end viewed in the direction of the force of gravity; (II) providing a contact tube (100, 110) with an upper and a lower end in the reactor, where the lower end of the contact tube is immersed in the liquid phase containing the second compound and in the contact tube a catalyst bed is present, which is adjusted to catalyze the reaction of the first and second precursor compounds to give the first compound; (III) introducing the first and second precursor compounds through the contact tube (100, 110), leaving the first compound formed in the contact tube from the lower end of the contact tube and coming into contact with the liquid phase it contains the second compound. |
