| titleOfInvention | A kind of tail gas treatment process of paranitrobenzoyl chloride |
| abstract | The invention provides a kind of tail gas treatment process of paranitrobenzoyl chloride, its step is as follows：Toluene solution will be added in reactor, to being filled with phosgene in reactor, and continue to be passed through phosgene simultaneously；To paranitrobenzoic acid is added dropwise in reactor, stirred when being added dropwise；Solution is passed through nitrogen and is once caught up with gas；By by once catching up with being dried by molecular sieve for gas；Dried gas is passed into recovery kettle, and chlorine is passed through to reclaiming in kettle, while set active carbon layer reclaiming in kettle, and by active carbon layer after dried gas mixes with chlorine；To reclaim kettle in be passed through nitrogen carry out it is secondary catch up with gas, the secondary gas for catching up with gas is then carried out into extraction phosgene by toluene or benzole soln；Gas after extraction is passed into NaOH solution.The present invention uses above-mentioned technique, is capable of to react the tail gas such as tail gas carbon monoxide for producing and be reacted generation phosgene again and is reclaimed. |
