At the time these products were thought to be related to the nitrated starch obtained a little previously by Henri Braconnot and called xyloidin; they are only related in so far as they are nitrates.
The nitrated product retains the outward form of the original cellulose.
Alkali sulphohydrates reduce guncotton, or other nitrated celluloses, completely to cellulose.
The so-called collodion cottons are nitrated celluloses, but of a lower degree of nitration (as a rule) than guncotton.
To prevent the freezing of nitroglycerin in dynamite it has been proposed to add various substances, such as chlordinitroglycerin, nitrated diglycerin or tetranitrodiglycerol, and also mono-and di-nitroglycerin.
