A comparison of thermal decomposition energy and nitrogen content of nitrocellulose in non-fat process of DSC and EA

[[abstract]]Investigations of nitrogen content and thermal decomposition activation energy (E a) of two different kinds of nitrocellulose (NC) products, NMNC and MNC from the non-fat and original processes of linters, respectively, were discussed. In this study, differential scanning calorimetry (DSC) and element analyzer (EA) are used, for the above two chemicals, along with the same nitration condition in use of sulfuric acid (H2SO4) and nitric acid (HNO3) mixing acid. E a was calculated by our induced model. According to our experimental results, the nitrogen content of NMNC/MNC was 11.71 and 11.55 mass%, in a low nitrogen content condition of mixing acid. The E a parameters were 319.91 (NMNC) and 347.27 (MNC) kJ mol−1, individually. They indicated that the non-fat process of a linter made a higher degree of stability than the others. This research also presents an efficient and accurate model of the thermal decomposition property evaluation for non-fat process of linters. The outcome is believed to be very useful for helping to understand, and be applied as, an inherently safer design during relevant NC manufacturing processes
