Method of manufacturing liquid phase for explosive slurries
Patent
·
OSTI ID:6845605
A liquid phase which is useful as a base for slurry explosives is made by reacting ammonium nitrate with formaldehyde in aqueous solution and dissolving additional unreacted ammonium nitrate in the aqueous solution, followed by addition of sodium nitrate to the mixture, raising the pH to a value between 4 and 7, and increasing the temperature to facilitate further mixing with other ingredients of the slurry explosive compositions. In an example, 430 Pt. by wt ammonium nitrate and 173 parts of 37% aqueous formaldehyde are reacted together, followed by addition of 48 parts of 97% sodium hydroxide. The results is a hot solution suitable for preparation of slurry explosives, having a pH between 5 and 5.8. (3 claims)
