STRAIGHT DYNAMITE 341
Munroe and Hall 13 also reported the following compositions
for typical ordinary and low-freezing ammonia dynamites, the
combustible material in each case being a mixture of wood pulp,
flour, and brimstone. Low-freezing dynamites at present in use
in this country contain nitroglycol or nitrosugar instead of the
above-mentioned nitrosubstitution compounds. In Europe dinitrochlorohydrin,
tetranitrodiglycerin, and other nitric esters are
used.

Taylor and Rinkenbach 15 report typical analyses of American
ammonium nitrate dynamite (I below) and ammonium nitrate
sodium nitrate dynamite (II below). These formulas really represent
ammonium nitrate permissible explosives, very close in their
