| titleOfInvention | A method of lufenuron intermediate is synthesized using continuous reaction |
| abstract | The invention discloses a kind of methods using continuous reaction synthesis lufenuron intermediate, this method utilizes micro passage reaction, lufenuron intermediate be can be realized without separation through addition, nitrification, three step successive reactions of pressure hydration, realize continuous production, total recovery > 92%, 99% or more purity >, the production cycle is substantially reduced simultaneously, is improved conversion ratio, is reduced side reaction, the dosage for reducing first step additive process expensive gases perfluoropropene, greatly reduces production cost；This invention also solves the danger that hydrogenation and the dangerous technique of nitrification are also easy to produce explosion；It is low also to solve the problems, such as that traditional autoclave hydrogenation process expensive catalyst Pt/C applies number simultaneously. |
