| titleOfInvention | The synthesis technique of 4,6 dinitroresorcinols |
| abstract | The present invention provides a kind of synthesis technique of 4,6 dinitroresorcinols, and raw material passes through three sulfonating reaction, nitration reaction and hydrolysis steps successively, wherein：Sulfonating reaction and nitration reaction carry out in pipeline reactor；Before sulfonating reaction, material liquid and sulfonated reagent, which respectively enter micro-mixer and mix and strengthen through strengthening mixer, to be mixed, and is entered back into pipeline reactor and is carried out sulfonating reaction, strengthens mixer and pipeline reactor passes through temperature regulating device temperature control；Before nitration reaction, sulfonated products feed liquid respectively enters micro-mixer with nitrating agent and mixes and through strengthening mixer reinforcing mixing, enters back into pipeline reactor and carries out nitration reaction, micro-mixer, reinforcing mixer and pipeline reactor pass through temperature regulating device temperature control.The quick mixing of the achievable material of the present invention and accurate temperature controlling, the total recovery of DNR reach as high as 87%, can be continuously produced, and improve production security, shorten the production cycle, reduce production cost, while environmentally friendly. |
