Chemical properties: When the purity is 98%, the melting point is 50-51°C, the boiling point is 128°C (0.4kPa), and the flash point is >110°C.
Application: dye intermediate
Production method: It is obtained by condensing ethylenediamine and acetic anhydride. In the acylation reactor, ethylenediamine is diluted with ice water to a concentration of about 20%, and then industrial acetic anhydride is slowly added. The reaction temperature is controlled at 20-25°C. After the reaction reaches the end point, it is neutralized with 30% sodium hydroxide solution to a pH of 6.5-7 to obtain the finished product.
