| titleOfInvention | A kind of pipe type continuously prepares the method for 2-MNQ |
| abstract | The invention discloses a kind of pipe type continuously and prepare 2-methyl isophthalic acid, the method of 4-naphthoquinones: the mixing of 2-methylnaphthalene, mineral acid and organic acid solvent is made into mixed solution, mixed solution and aqueous hydrogen peroxide solution are respectively through after volume pump, mix through Y type jet mixer, mixed material enters tubular reactor and reacts, controlling reacting liquid temperature is 50 ~ 120 DEG C, and the reaction time in tubular reactor is 5 ~ 20min; Tubular reactor outlet gained material enters in the crystallization kettle of the water placing 5 ~ 10 DEG C in advance after cooling, and separate out solid, filter, filter cake, through being washed to neutrality, is dried, obtained described 2-MNQ.The inventive method has the advantages such as equipment is simple, throughput large, constant product quality, possess reaction time and easy temperature control system, side reaction is few, simple to operate, security is good advantage, easily be automated control, be conducive to suitability for industrialized production, can production cost be reduced. |
