Process for preparing isocyanates |
| abstract |
The invention relates to a process for preparing isocyanates, comprising (a) the reaction of at least one amine with phosgene in the gas phase in a reaction zone and (b) the subsequent cooling of the reaction gases in a cooling zone by means of indirect cooling, the cooling medium which absorbs the heat of the reaction gases being conducted in countercurrent to the product stream at least in the region of the highest temperature in the cooling zone. |
