Sätt att framställa ADN-prills lämpliga för användning i ett polymersystem

摘要

Improved production method for liquid-phase prills of ammonium dinitramide (ADN) having high homogeneity comprises the use of ultrasonic energy. A method for producing prills of ADN, comprising melting and dispersion of ADN in a non-polar medium to obtain droplets, cooling to solidify the droplets into prills and separating the prills. Ultrasonic energy is supplied to the non-polar medium during dispersion. An Independent claim is included for a polymodal mixture of ADN prills comprising prills have particle size of less than 40 mum.
