    摘要： The present invention relates to a process for the production of an isocyanate corresponding to the formula R(NCO)n wherein R represents a (cyclo)aliphatic or aromatic hydrocarbon residue having up to 15 carbon atoms, preferably 4 to 13 carbon atoms, provided that there are at least 2 carbon atoms arranged between each of the nitrogens and n represents the number 2 or 3, by a) separately heating an amine corresponding to the formula R(NH2)n, wherein R and n are as previously defined, in vapor form, optionally diluted with an inert gas or the vapors of an inert solvent, and phosgene to temperatures of 200° C. to 600° C., b) continuously reacting the optionally diluted amine and phosgene in a reactor which has a reaction chamber that does not have moving parts, wherein the reactor has a diameter D and centrally located in the reactor is a nozzle having an orifice diameter d, i) by introducing the optionally diluted amine into the reactor through the nozzle and by introducing phosgene through the annular space around the nozzle such that the amine and phosgene flow in parallel through the reactor and ii) mixing and reacting the amine and phosgene to form the isocyanate of formula I) by introducing the amine through the orifice into a stream of phosgene in the reaction chamber, wherein the gas velocity of the optionally diluted amine is higher than the gas velocity of phosgene and the ratio of the narrower nozzle diameter d to the reactor diameter D is from 5% to 45%.

    摘要： Isocyanates are produced in the gas phase in a manner such that temperature fluctuations over time and temperature distribution asymmetry are prevented. In this improved process, performance of the reaction in tubular reactors is accomplished by flow-related measures such as homogenization and centering of the educt streams. The formation of polymeric secondary products, which result in baked-on deposits in the reactor and a reduction in reactor service life, is consequently prevented.
