National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Nitrate Ester Decomposition and Degradation of Molecular Weight in Nitrocellulose from Thermal Decomposition of PBX-9404 Below 100 exp 0 C.

Abstract The thermal decomposition of nitrate ester (-ONO sub 2 ) in the nitrocellulose (NC) binder of PBX-9404 was studied. Evidence was found that the tri-esterified NC subunits decompose most readily; by calculating the relative populations of mono-, di-, and tri-esterfied subunits and monitoring NC composition as a function of (-ONO sub 2 ) loss, the extent of degradation of the NC molecular weight was estimated. Decomposition of (-ONO sub 2 ) obeyed second-order kinetics, and the activation energy for decomposition (26.1 kcal/mol) agreed with values calculated on the basis of weight loss or the amount of evolved gas.
