| titleOfInvention | Surfactant for vehicle urea solution and its preparation method and application |
| abstract | The invention discloses a surfactant for vehicle urea solution, a preparation method and application thereof. The surfactant used for the vehicle urea solution is fatty amine polyoxypropylene polyoxyethylene ether nonionic surfactant, and its preparation method is 1) putting fatty amine or fatty diamine or a mixture of the two into reaction with catalyst I In the kettle, replace the air in the kettle with nitrogen, vacuumize, heat up, and slowly add propylene oxide to react to obtain the propoxy polyether compound; 2) make the propoxy polyether compound and the catalyst II in the kettle under the similar conditions of step 1) , slowly add ethylene oxide, adjust the liquid in the kettle to be neutral after the reaction is completed, remove the material liquid and centrifuge to obtain the fatty amine polyoxypropylene polyoxyethylene ether nonionic surfactant. The method is simple and easy to realize large-scale production. Adding the prepared surfactant directly into the vehicle urea solution can improve its urea dispersibility and atomization effect, increase the conversion efficiency of NH 3 , and avoid the blockage of the SCR system. |
