| titleOfInvention | A kind of method of continuous production ibuprofen ester |
| abstract | The present invention relates to a kind of methods of continuous production ibuprofen ester, belong to field of medicine and chemical technology;Include the following steps；One, the washing ketal that condensation reaction generates, by being pumped into level-one rearrangement reactor, catalyst squeezes into level-one rearrangement reactor by pumping, and the laggard rearrangement reaction of solvent is added；Two, rearrangement reaction successively carries out in multiple concatenated continuous rearrangement reactors, and reaction of high order is overflow discharging；Three, the gas phase of reaction of high order enters condenser, and condensed material enters return tank；The process that the solvent having more enters condensation reaction from return tank side overflow.Four, rearrangement solution is discharged by afterbody rearrangement reactor overflow, into subsequent processing；The reaction time is shortened, the generation of rearrangement process side reaction is reduced, the yield of ibuprofen ester is improved to 95% or more. |
