FIELD: explosives. ^ SUBSTANCE: invention relates to technology of preparing components of gun powders, mixed solid propellants, and mixed blasting materials. Nitroisobutylglycerol nitrate is prepared via nitration of nitroisobutylglycerol with sulfuric acid/nitric acid mixture. Particularly, nitroisobutylglycerol is dissolved in acid mixture enriched with nitric acid and thus formed nitroisobutylglycerol trinitrate is treated with sulfuric acid or oleum and then stabilized in inert solvent (dichloromethane or dichloroethane) with anhydrous neutralizing agent: calcium oxide or calcium carbonate. Product is characterized by density at least 1.63 g/cc and high heat resistance with initial intensive decomposition temperature not below that that of standard nitroglycerin (135-140°C). ^ EFFECT: improved quality characteristics of product. ^ 1 tbl, 3 ex |
