production method | (1) wurvex method: nitric acid (100%) and hexamethylenetetramine (urotropine) as the raw material, the amount of nitric acid is 11 times that of hexamethylenetetramine, the reaction temperature is controlled below 30 ℃, the reaction of hexamethylenetetramine by nitric acid hydrolysis (Nitrolysis) after the role of RDX, NH3 and formaldehyde. (2) zberre-xeles-rose method: formaldehyde and ammonium nitrate were added to acetic anhydride, and the reaction temperature was controlled at 70 °c. Because this method requires a large amount of acetic anhydride and low yield, the synthesis method is not ideal. (3) Barkman method: a combination of the wuerweiss method and the zbele-Nesler-Ross method is used, and therefore Barkman called this method a combination method. The raw materials used in this method are hexamethylenetetramine, ammonium nitrate, nitric acid and acetic anhydride. The yield of the Barkman method was about 80%, and the obtained RDX had a melting point of about 190 ° C. And contained about 10% of HMX. Since the amount of acetic anhydride and nitric acid used in the Barkman method is small, and the yield of this method is high, the cost of using RDX is reduced. (4) The wollatan method: formaldehyde and potassium sulfamate will produce potassium methylene sulfamate. Potassium methylene amino sulfonate is a trimer, and this cyclic compound is nitrated with 80% fuming nitric acid and 20% sulfur trioxide as nitrating agent to obtain RDX. The yield of the wolrham method is 80% to 90%. |
