Nitroglycerine vapour pressure

For the vapour pressure of nitroglycerine different data are to be found in the literature which are incompatible and depend to an appreciable extent upon the method of measurement chosen. Thus the vapour pressure of nitroglycerine at 2S°C was found by ChiaravigUo and Corbino [35] to be below 0.00012 mm Hg. 

Applying the statistical method they have calculated that at 20°G the vapour pressure of nitroglycerine is 0.0009 mm Hg. 

The vapour pressure of nitroglycerine has also been determined by Crater [39] and Brandner [40]. The latter attempted to remove the discrepancies which exist between the values published by different investigators. Thus the data of Brandner... 

Using his own data, Brandner has calculated the heat of evaporation of nitroglycerine to be AHv = 19.17 kcal/mole. The same author has investigated the vapour pressure of nitroglycol (see p. 143) and calculated that of nitroglycerine-nitroglycol mixed solutions. The results are collected in Table 13. 

Poisoning can take place either from inhalation of the vapour of nitroglycerine (the very low concentration corresponding with the vapour pressure at room temperature is sufficient) or as the result of penetration through the skin or through the mucous membranes (the latter occurs with particular ease). 

The vapour pressure of solutions of nitroglycol in nitroglycerine has been reported on p. 44 (Table 13). 

In a publication of Rinkenbach [13] the volatility of nitroglycol was reported to be 2.2 mg/cm2/hr. This value is 20 times greater than that for nitroglycerine. Since it possesses a sufficiently high vapour pressure at 100°C nitroglycol can be slowly steam distilled. 

Dinitrodiglycol is more volatile than nitroglycerine. Its vapour pressure is... 

The action of PETN on the human system is the same as that produced by all other nitric esters. Nevertheless inhalation of PETN is not dangerous, as its vapour pressure is negligible. Similarly, breathing small amounts of penthrite m the form of dust causes no deleterious effect owing to its low solubility. Lazarev [23] reports the toxicity of pentaerythritol tetranitrate to be lower than that of nitroglycerine.
