Abstract

A stabilized blasting explosive is prepared by incorporating with granular ammonium nitrate an inclusion compound of urea and an aliphatic hydrocarbon or a fatty acid. The explosives do not segregate and retain their sensitivity on storage. From 3 to 6 parts by weight of urea may be associated with 1 part of the hydrocarbon or acid and the inclusion compound may comprise 2 to 25% by weight of the explosive. In one method of preparation, the hydrocarbon or acid is added with stirring at room temperature to an alcohol solution of urea; the inclusion compound crystallizes out, is separated by filtering and drying, and then mixed with ammonium nitrate. In an alternative process, the inclusion compound is formed in situ by adding an alcohol solution of urea, or urea moistened with alcohol, to a mixture of ammonium nitrate and the hydrocarbon or acid, and the solid filtered off and dried if necessary. In examples, the following are used in addition to urea: finely ground or agricultural grade ammonium nitrate, methanol or ethanol, C9 to C20 paraffinic hydrocarbons, dodecane, 1-decene, eicosane, kerosene, or oleic acid.ALSO:Inclusion compounds of urea and an aliphatic hydrocarbon or a fatty acid, useful as stabilizers for ammonium nitrate explosives (see Division Cl), are prepared by stirring a lower alcohol solution of urea with the hydrocarbon or acid, preferably at 55 DEG -60 DEG C. From 3 to 6 parts by weight of urea may be associated with 1 part of hydrocarbon or acid. Specified hydrocarbons are decane, undecane, dodecane, tridecane, tetradecane, pentadecane, hexadecane, heptadecane, octadecane, nonadecane, eicosane, 1-decene, kerosene, and a mixture of C9 to C20 paraffin hydrocarbons; specified acids are stearic, oleic, linoleic, and linolenic acids. The inclusion compound may be formed in situ mixed with the ammonium nitrate.
