Solventless Cordite

In certain operations, such as the rolling of solventless cordite, experience shows that fires must sometimes be expected. Under these circumstances it is usual to provide a water drenching system operated by a photoelectric device. Rapid application of a mass of water successfully limits the fire to the material originally enflamed. 

Huffington [24] studied the combustion of solventless cordite containing 56% nitrocellulose (12.2% N), 29% nitroglycerine, 4.5% carbamite and 10.5% dinitro-toluene plus 2.45% cryolite and 0.35% volatile matter. 

These experiments appear to throw a new light on the structure of solventless cordite. It seems that nitroglycerine is present as minute globules and that the second type of intermittent burning is due to the non-thermal explosion of these globules. 

After World War I the manufacture of solventless powder was started in other countries France under the name of powder SD (sans dissolvent), Great Britain as Cordite SC (solventless cordite) and the U.S.S.R.

Cordite SC (Cordite Solventless, Carbamite) The use of a solventless Cordite was suggested at a conference at Watham Abbey in 1914. The composition proposed consisted essentially of NG soluble NC. To facilitate gelatinization, which was effected by heating rolling without the use of a vol solv, urethane derivs benzyl-phenylether (qv) were added. These compds were found to exert also a stabilizing action.
