Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 1187-42-4, name is Diaminomaleonitrile, A new synthetic method of this compound is introduced below., Quality Control of Diaminomaleonitrile
Example 1-1; Methanol, in an amount of 216 mL, was placed in a four-necked flask with a volume of 500 mL, and 108.1 g (purity: 98.7percent, 0.987 mol) of DAMN and 116.73 g (1.100 mol) of trimethyl orthoformate were added thereto. p-Toluenesulfonic acid, monohydrate, in an amount of 190 mg, was added to the aforementioned mixture, and the reaction mixture was stirred while maintaining the temperature at 65¡ãC. 45 minutes after stirring was started, crystals of MMD were precipitated, and completion of the reaction was suggested. After the reaction mixture was stirred for 1.5 hours, the reaction mixture was cooled to 5¡ãC. The crystals were filtered and washed with 100 mL of cooled methanol, followed by drying. Thereby, 118.56 g (0.852 mol, yield = 80percent) of methyl N-(2-amino-1,2-dicyanovinyl)formimidate (MMD) was obtained.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
