dc.description.abstract |
Nitrocellulose based propellants are the main ingredient of munitions specifically in smokeless
powder which have their prescribed shelf life. Their shelf life mainly depends upon the type and
quantity of stabilizer used during formulation. These stabilizers are not only capable to improve
shelf life despite it can improve the efficiency and performance manifold. After expiry of the
stabilizer contents their usage and storage are not recommended due to erratic behavior and
thermolysis which may lead to autoignition. Auto Catalysis reaction taken place during their
storage over a period of time render the propellants more sensitive which is not required for the as
it not only damages the equipment but also stack holders can also be victimized. Presently open
burning operations are being carried out for propellants disposal as a demilitarization technique
which is unsafe, uneconomical and un-environmental friendly. Dozens of techniques have been
developed or in developing stage to address these issues of disposal. Owing to the difficulties
associated with the open burning the proposed technique of Alkaline Hydrolysis is suggested to
be carried out to neutralize the energetic contents for their disposal. Moreover, neutralization
results in chemical conversion of the nitrocellulose into a value-added fertilizer additive which
have enormous agricultural applications. The paper will be unfolding with basic understanding of
Nitrocellulose based single base propellants followed by the experiment’s methodology dwelling
around the alkaline hydrolysis. Subsequently interpreting the characterization technique; Fourier
Transform Infrared (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM)
results along with application of the product through Pot Analysis. A strong alkaline reagent
Potassium Hydroxide will be used for breaking the chains of cellulose nitrate polymer. Phosphoric
Acid and Humic Acid would be used as additives to impart soil conditioning properties. The
developed fertilizer subjected to pot testing for wheat and maize crops to assess the various aspects
of agricultural application. The achieved results were encouraging which are scientifically
supported. Statics were interoperated through ANOVA software to find out the deviation in
replicates of each treatment by using a model of completely randomized design (CRD). |
