A model was developed to describe the nitration of cellulose in mixed acids used in the production of military grade nitrocellulose. Acid dissociation, swelling, diffusion, and chemical reaction were considered to model the nitration of industrially important cellulose materials for given reaction times and conditions. This model is supported by experimental work conducted to measure the dynamics of swelling and diffusion in wood pulp slivers, and the model was validated using the results of lab‐scale nitration reactions. Microcomputed tomography was also used to perform a structural analysis of wood pulp slivers that were cut on industrial, rotary cutting machines to evaluate features that may influence the reactivity of these materials.

用于军事用途的工业规模硝化纤维素生产的化学反应建模

开发了一个模型来描述军事级硝化纤维素生产中所用混合酸中纤维素的硝化作用。在给定的反应时间和条件下，酸解离，溶胀，扩散和化学反应被认为可以模拟工业上重要的纤维素材料的硝化作用。该模型得到了测量木浆条膨胀和扩散动力学的实验工作的支持，并使用实验室规模的硝化反应结果对模型进行了验证。微计算机断层扫描还用于对在工业旋转切割机上切割的木浆条进行结构分析，以评估可能影响这些材料反应性的特征。
