Analyzing the synthesis route of 88-96-0

At the same time, in my other blogs, there are other synthetic methods of this type of compound, Phthalamide, and friends who are interested can also refer to it.

Reference of 88-96-0, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 88-96-0 name is Phthalamide, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

1) Synthesis of phthalimide potassium A round-bottom flask containing 3200 mL dehydrated alcohol was added with 160.0 g phthalamide, and heated and refluxed for 0.5 h, until only a small amount of raw materials was not dissolved. The resulted hot solution was added into 61.0 g potassium hydroxide solution (including 60 mL water and 180 mL alcohol) by decantation, by which a white precipitate was formed immediately. Then the solution was cooled and filtered to obtain filtered residue, and alcohol was recycled. The filtered residue was washed with 400 mL acetone, 196.0 g phthalimide potassium was obtained, and the yield was 98.0%.

At the same time, in my other blogs, there are other synthetic methods of this type of compound, Phthalamide, and friends who are interested can also refer to it.
