Trimethyleneglycol dinitrate is less volatile than nitroglycol, but more
so than nitroglycerine. Its solubilities in various solvents are similar to
those of nitroglycerin. Like nitroglycerine, it forms satisfactory gels with
nitrocelluloses. It causes headaches. Trimethyleneglycol dinitrate is
prepared by nitration of trimethylene glycol with nitric acid or mixed
acid at 0–10 °C. It is less impact-sensitive than nitroglycerine and is
much more stable to store. It is now not longer used.
