Abstract: The invention relates to a process for preparing methylamines by gas-phase reaction of methanol and ammonia as starting materials at a pressure in the range from 15 to 30 bar in the presence of heterogeneous catalyst. The starting materials are vaporized in one or more heat exchangers (1, 2, 3), superheated to produce a feed gas stream and subsequently fed into a reactor (4), with the mixing of the starting materials being able to be carried out in the feed stream to one of the heat exchangers (1, 2, 3) or at any desired position in a heat exchanger (1, 2, 3). A product gas stream comprising monomethylamine, dimethylamine and trimethylamine and also reaction by-products is taken off from the reactor (4). To control the reactor inlet temperature of the starting materials to a temperature in the range from 360° C. to 370° C., all or some of the feed gas stream or the product gas stream is passed through an adjustable valve (5) in order to vary the pressure and thus the condensation temperature.

Abstract: The invention relates to a process for the preparation of tetrasubstituted ureas by reaction of the corresponding amines with phosgene in the presence of an aqueous inorganic base at a temperature in the range from 0 to 150° C., which comprises: feeding the corresponding amine, the phosgene and the aqueous inorganic base on average continuously to the reaction apparatus, forming a two-phase system in the reaction apparatus through the choice of the tetrasubstituted ureas to be prepared, through the mixing ratios of the substances and substance mixtures to be fed in, through the temperature during the reaction and, where appropriate, through the feed of an organic solvent which is not completely miscible with water, and discharging the reaction mixture on average continuously from the reaction apparatus.
