In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 89-40-7, name is 5-Nitroisoindoline-1,3-dione belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below. Product Details of 89-40-7
In a 250 ml two-necked flask, 40 ml of absolute ethanol and 10 ml of distilled water, 14.56 g (0.26 mol) of iron powder and 1.643 g (0.031 mol) of ammonium chloride were added.10g (0.052mol) of 4-nitrophthalimide was added under stirring without nitrogen protection; the temperature was set at 65 C, and the reaction was about 4 h.TCL shows that the disappearance of the starting point of the reaction is completed; the pH of the solution is adjusted to 9-10 by sodium carbonate, the filter cake is filtered and dried, and extracted with 100 ml of absolute ethanol (85 C) for 3 times.Ethanol distilled under reduced pressure to give a yellow solid 7.5g, yield 89.03%.
The synthetic route of 89-40-7 has been constantly updated, and we look forward to future research findings.
