Abstract
In view of current domestic ADC foaming agent acid production technology for biurea existing large washing wastewater and difficulty to deal with issues,and by analyzing biurea synthesis mechanism,we have carried out biurea new production technology research and development. By using of pure hydrazine acid-free condensation process,we reduced the amount of waste water from the source system and impurity contents,and the difficulty of wastewater treatment. At the same time,by optimizing process parameters such as the concentration of the reaction system,temperature,catalyst etc,we have explored a new continuous acid-free contract production technology for biurea. The new process can be done for condensation mother liquor recycling,and resolving waste water treatment in acid condensation process and other issues successfully.
