Nitrocellulose melting temperature

Experiments on burning nitrocellulose (deflagration and explosion) were carried out in World War II by Rideal and A. J. B. Robertson [91]. One interesting observation they made was that nitrocotton heated for a long time at 200°C under a pressure of 50 mm Hg liquefied shortly before the explosion. Nitrocellulose has been known to melt while being stabilized in an autoclave at an elevated temperature, since it overheats if there is too little water in the autoclave (on melting nitrocellulose, see p. 242). 

Place 170 grams of ozokerite wax into a 500-milliliter beaker and then heat to 90 Celsius to melt the wax. After the wax has melted, add 2 grams of dry lecithin. Afterwards, raise the temperature to 110 Celsius. Then, rapidly stir the molten mixture at 110 Celsius for 90 minutes. After 90 minutes, cool the mixture to 90 Celsius. Then prepare a nitrocellulose mixture by mixing 186...
