为了实现降解TBP溶剂洗涤过程的无盐化,选用了碳酸肼作洗涤剂。本研究工作对碳酸肼的制备方法及其稳定性作了较详细研究。探索了在常压及二氧化碳各种气压条件下(2×10~5Pa—6×10~5Pa)制备碳酸肼的可能性。实验证明,用大于2×10~5Pa
In order to achieve the degradation of TBP solvent washing process without salinization, the choice of carbonic acid hydrazine as a detergent. The research work on the preparation of carbonic acid hydrazine and its stability in more detail. The possibility of preparing hydrazine carbonate under various pressures of atmospheric pressure and carbon dioxide (2 × 10 ~ 5Pa-6 × 10 ~ 5Pa) was explored. Experiments show that with more than 2 × 10 ~ 5Pa
