METHOD FOR OCTOGEN RECRYSTALLISATION

摘要

FIELD: chemistry. ^ SUBSTANCE: invention refers to the method for octogen recrystallisation by the way of its partial dissolution in the water solution of -caprolactam during heating with following cooling differing in the fact that octogen beforehand disintegrated up to specific surface area 2800 cm2/g - 4000 cm2/g is processed in the 70% water solution of -caprolactam with mass ratio of solution of -caprolactam to octogen being equal to 3-10:1, heated up to the temperature 5080C, allowed and the cooled to 1025C. The said method of octogen recrystallisation allows to obtain the -octogen of necessary fractions with average particle size dav=15020 mcm and 5010 mcm and acidity less than 0.03% with feasible and economic way. ^ EFFECT: providing of feasible and economic method for preparation of -octogen necessary fractions ^ 3 cl, 4 ex
