Description
4-NFM get typically the action of concentrated nitric acid (90-100%) to a solution of N-methylphthalimide (MT) in concentrated sulfuric acid or mixtures of otnoshenii MF:H2SO4:HNO31:3,6:1.2 V for 1-1 .5 hours and Then the reaction solution is placed in a special extractor to extract the target product with methylene chloride. The extraction is carried out in two steps methylene chloride. The total extraction time of 8.5 hours, the Extract is then passed through a column of silica gel to remove the acid, after which the methylene chloride is distilled off in vacuo in a rotary film (evaporator and receive microproduct with access 89,3% 94,4% 4-MFD, 5% 3-MFD and 1% MF. The patent provides a method of regenerating sulphuric acid.
