| titleOfInvention | Synthetic method for N,N'-diisopropyl carbodiimide |
| abstract | The invention discloses a synthetic method for N,N'-diisopropyl carbodiimide. The method includes the following steps that (1) carbon disulfide and isopropyl amine are added into an alkaline solution, the mixed solution is heated to the set temperature, after a constant-temperature reaction is conducted for set time, a mixed solution A is obtained; (2) the mixed solution A and hydrogen peroxide are mixed and heated to preset temperature, after a constant-temperature reaction is conducted for preset time, a mixed solution B is obtained; (3) in an alkaline environment, the mixed solution B, dichloromethane and the isopropyl amine are mixed evenly, then a sodium hypochlorite solution is added to conduct an oxidizing reaction, separation and purification are conducted to obtain the N,N'-diisopropyl carbodiimide. The synthetic method for the N,N'-diisopropyl carbodiimide is mild in reaction conditions, high in yield and simple in aftertreatment and can achieve large-scale industrial production easily. |
