Property and Preparation of Glycerol Nitrate

Glycerol nitrate, also called as mononitroglycerin, has a and P isomers. Their melting point and boding point are shghdy dilferenL The discrimination between two isomers is listed in Table 5.10. 

Glycerol nitrate is a very stable compound. It would be decomposed at 100 °C and be exploded at 170 °C in a sealed container. 

Glycerol nitrate is a weak explosive with obvious negative oxygen balance. Its explosive heat (water vapor condition) is about 1815.9 J/g. Its shock sensitivity is low, thus that it can be a desensitizer. The instability for detonation is related to its physical status. The lead-block value of glycerol nitrate is only 75 cm. The crystal of glycerol nitrate is easy to be detonated with lead-block value of 245 cm.
