Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 603-62-3, name is 3-Nitrophthalimide, This compound has unique chemical properties. The synthetic route is as follows., COA of Formula: C8H4N2O4
3-Nitrophthalimide (LOOGR) was taken into a hydrogenation vessel and dissolved using 500ML of dimethylformamide. Raney nickel catalyst (20gr, wet) was added to the solution and subjected to hydrogenation conditions initially at 20-30C UNDER 20-40psi. After the exothermic nature of the reaction was over, hydrogen pressure was increased to 40-60psi and the temperature to 40-50C. After the hydrogen uptake is over sample was drawn from the reaction mass and checked for the absence of 3-nitrophthalimide by TLC. The reaction mixture was filtered while hot and the catalyst removed by filtration. Solvent was removed from the filtrate under reduced pressure at 60-80C. Water (500ML) was added to the residue and the mixture stirred for 20-30MIN. The product was isolated by filtration and dried at 60-70C to get a yellow crystalline solid of 3-aminophthalimide (80gr, 95%). Melting point: 262-4C.
According to the analysis of related databases, 603-62-3, the application of this compound in the production field has become more and more popular.
