“…A calibration plot was generated by plotting the literature values for the heat of combustion for samples of a known percent nitrogen composition versus the percent nitrogen in the sample; 0% (determined in this study), 12.6% (11), 13.45% (11), and 14.14% (11) (figure 3). The resulting graph yielded a straight line, making it reasonable to determine the estimated nitrogen content of the NC, 4DNC, and 18DNC samples without the need of a FeCl 2 -TiCl 3 titration (12,13). While other methods for nitrogen content determination are known, see Norwitz and Chasan (14).…”

SynopsisA two-step procedure for the preparation of methyl cellulose nitrate is described. The heterogeneity of the methylation step is reflected in the nonuniformity of the products obtained by nitration with either 98% nitric acid or a solution of 98% nitric acid in methylene chloride. On the basis of the experimental data it is calculated that methyl cellulose having a minimum degree of substitution of 1.8 is required for the preparation of a uniformly substituted methyl cellulose nitrate.

Afin d'améliorer les délais de réponse et la productivité, une méthode d'analyse autre que la méthode Dewarda était recherchée pour doser I'azote nitrique des nitrocelluloses, avec des succès divers mais sans obtenir la précision demandée. Les auteurs ont étudié I'influence des paramètres régissant le dosage par potentiometrie de l'azote nitrique par le sulfate ferreux, tels que la température, la stabilité des réactifs, les concentrations, I'agitation. Cette étude a permis de concevoir un prototype de dosage entitrèment automatisé, permettant d'obtenir un temps de réponse de l'ordre de 20 minutes et une précision comparable à celle de la méthode Dewarda. Elle s'applique à la nitrocellulose. aux esters nitriques et à la nitroguanidine.
