On the compaction of polynitro compounds

Thread Content

***Chlorobenzene reacts with liquid caustic to produce sodium *** phenolate; the solution of sodium *** phenolate is then pumped using compressed air to a downstream reaction vessel for further reactions. What I would like to ask is: 1. Pure *** sodium phenolate belongs to **; is its solution explosive? If it is explosive, is it related to the concentration? 2. The explosive hazard of polynitro compounds arises upon impact or exposure to high temperatures; what is the threshold temperature for high temperatures? (The operating temperature for this reaction is 95°C.) 3. Another issue is whether it is possible to use air pressure for feeding materials. Given the explosion that occurred in a chemical plant in Lianyungang, the accident analysis indicated that it was caused by the unauthorized replacement of nitrogen pressure with air pressure for feeding materials; this situation is quite similar to what happened in Lianyungang.
