Nitration in mixtures and solutions including inactive substances

NITRATION IN MIXTURES AND SOLUTIONS INCLUDING INACTIVE SUBSTANCES 

The earliest attempt to nitrate cellulose in mixtures comprising inactive substances was made by Rogovin and Paradnia [46]. The experiments were aimed at investigating the possibility of replacing the large excess of sulphuric acid which does 

Rogovin and Paradnia substituted carbon tetrachloride or pentane for a part of the mixed add, and obtained nitrocellulose with different nitrogen values. With a low water content, and a ratio HN03 H2S04 of 3 1, and by varying the proportion of the inert substance for 75-87%, they obtained nitrocellulose of different nitrogen contents.  

Kenyon et ctl. [47] published a graph (Fig. 127) showing the effect of the nitric 

In addition, there are a few references in the literature describing experiments to nitrate cellulose in media comprising solvents resistant to nitration such as chloroform and other chlorinated hydrocarbons.
