Ultrasonic washing and deacidification process for cyclotrimethylene trinitramine

The invention provides a washing and deacidification process for cyclotrimethylene trinitramine. According to the process, an ultrasonic technology is adopted to wash acid-containing cyclotrimethylene trinitramine, and the process flow mainly comprises the steps of ultrasonically washing acid-containing cyclotrimethylene trinitramine, filtering cyclotrimethylene trinitramine, and drying cyclotrimethylene trinitramine. Acid-containing cyclotrimethylene trinitramine is effectively washed, filtered and dried under optimal ultrasonic washing process conditions, and then, a cyclotrimethylene trinitramine product which has the acidity lower than 0.05% and meets the requirements of international military standards can be obtained. The process has the advantages that the washing process is simple, the washing time is short, the energy consumption is low, the washing effect is excellent, and the problems of the original cyclotrimethylene trinitramine washing processes that the washing time is long, the energy consumption is high and the water consumption is large are solved.
