NITROMANNITE 23?<br />

While its stability at ordinary temperatures is such that it can<br />

be used commercially, at slightly elevated temperatures it is distinctly<br />

less stable than nitroglycerin. Nitroglycerin will tolerate<br />

heating in a covered glass vessel for several days at 75° before<br />

it begins to give <strong>of</strong>f acid fumes; nitroglycol, methylglycol dinitrate,<br />

<strong>and</strong> trimethylene glycol dinitrate are more stable yet,<br />

but nitromannite decomposes after a few hours <strong>and</strong> evolves red<br />

fumes. If a small quantity is heated, it decomposes at once at<br />

about 150° with copious evolution <strong>of</strong> nitrous fumes but ordinarily<br />

does not deflagrate. With larger samples deflagration occurs at<br />

160-170°.
