    摘要： The invention relates to a method for producing isocyanates by converting the corresponding amine with phosgene in the gas phase, in the presence of an inert medium as applicable, wherein phosgene and amine are first vaporized and then overheated to reaction temperature, the overheated phosgene and amine are mixed and added to a reactor wherein the phosgene and the amine are converted to isocyanate, wherein the dwell time of the phosgene at temperatures greater than 300°C equals a maximum of 5 sec and/or the temperature of heat transfer surfaces in contact with the phosgene is 20 K above the phosgene temperature to be set at maximum. The invention further relates to a device for producing isocyanates by converting the corresponding amine with phosgene in the gas phase.

    摘要： The invention relates to a method for producing isocyanates by reacting the corresponding amines with phosgene in the gaseous phase, optionally in the presence of an inert medium. According to said method, the amine and the phosgene are first mixed and are reacted to isocyanate in a reactor, a reaction gas (1) leaving the reactor and containing isocyanate and hydrochloric acid being cooled in a quencher (3) by adding a liquid quenching medium (5), resulting in a mixture of reaction gas and quenching medium as a product stream (7). The quenching medium (5) used is a mixture which contains at least one solvent and the isocyanate and which is removed from the production process, solid particles being removed from the quenching medium (5) before it is added to the quencher (3).

    摘要： The invention relates to a method for producing isocyanates by reacting the corresponding amines with phosgene in the gas phase, optionally in the presence of an inert medium, wherein the amine and the phosgene are first mixed and reacted in a reactor to form isocyanate, wherein a reaction gas leaving the reactor and containing isocyanate and hydrochloric acid is cooled in a quench through the addition of a liquid quench medium, whereby a mixture of reaction gas and quench medium results. The amount of quench medium added is made to be such that the temperature of the mixture of the reaction gas and the quench medium, said temperature in equilibrium with the quench, is above the dew point of the gas contained in the quench.

    摘要： The invention relates to a method for producing isocyanates by reacting the corresponding amines with phosgene in the gas phase, optionally in the presence of at least one inert medium. Said phosgene is guided into a reactor (21) through a first inlet and the amine is guided through a second inlet of an ejector (1). The first inlet and the second inlet join in a mixing area (17) in which the phosgene and the amine are mixed to form a reaction mixture. A diffuser (19) that is joined to the mixing area (17) increases the pressure and the temperature of the reaction mixture consisting of phosgene and amine.
