    • Process for preparing isocyanates by reacting the corresponding amines comprised in at least one feed stream A with phosgene comprised in at least one feed stream P in a reactor plant comprising at least one mixing zone and at least one reaction zone, wherein feed stream A and/or feed stream P optionally comprise one or more inert materials and, during periods of time in which the flow S
      x of the amines used is below the flow S
      0 of the amines used during operation at the nominal capacity of the reactor plant, (i) the ratio of phosgene to amine is increased and/or (ii) the concentration of the inert material or materials in the amine-comprising feed stream A and/or the phosgene-comprising feed stream P is increased compared to operation at the nominal capacity of the reactor.
    • 通过使包含在至少一种进料流A中的相应胺与包含在至少一种进料流P中的光气在包含至少一个混合区和至少一个反应区的反应器装置中反应来制备异氰酸酯的方法,其中进料流A和/ 或进料流P任选地包含一种或多种惰性材料,并且在所使用的胺的流量S x低于在反应器设备的额定容量下操作期间使用的胺的流量S 0的时间段期间, )光气与胺的比例增加和/或(ii)与标称容量下的操作相比,含胺的进料流A和/或含光气的进料流P中的一种或多种惰性材料的浓度增加 的反应堆。
